Title: 93 LX project
Post by: servo765 on December 10, 2012, 09:58:17 pm
SBFs run in the family, so when my time came, I tracked down a black on black LX fox and proceeded to do a mish-mash of random bolt-ons that make no sense having learned a touch.  I have no idea what I'm doing, but I am supporting the local used parts economy and having fun ;D

Stock bottom end 302 on its last legs
E cam (/groan)
Pro-Comp heads (/groan)
Recently gutted EFI system (anyone need an EEC harness near P'cola, I have one in decent shape you can have)
RPM Air Gap
Ancient MSD 6AL with an MSD vac advance distributor
Electric fan/thermostat controller
RPM Air Gap intake
Road Demon 625
BBK equal length shorties into 3" exhaust
Tremec 3550 / 4.10 gears
5-lug swap
Smells like beer inside
Corbeau GTS-II seats (no more gangster lean!)

Currently wiring up a bitchin 130 amp alternator and wrapping up the carb swap.  Running again before Christmas i hope!

I'm in the P-cola area.............i'll take the harness if your giving it away, have a buddy that can use it for a project he has waiting in line...........are you new to the area? "Local" 1/8th. mile track will be opening soon, shoot me a PM when you get a chance...........

I "completed" my EFI-to-carb swap today.

Finding the power wire to the fuel pump was kind of a pain in the balls but that was the final hurdle.

Does anyone know of a bypass style regulator that will successfully output 7psi with the stock fuel pump, pickup and lines?  I read tons of posts of people who were able to "put on a good fuel pressure regulator" and use that setup.  Apparently an 80$ reg isnt good enough.  The 'Holley Billet Adjustable Fuel Pressure Regulator' that i bought is not up to the task and the carb doesn't like 12psi.  Maybe i'll try the mallory that everyone was talking about.

I am also learning for the second or time not to buy used parts as the 6AL box is seemingly not outputting a damn thing.  I will recheck my wiring in the daylight before I call this dude and give him the business but it looks like i got burned.

Check the pins in the magnetic pickup harness. Seen them loosen or go bad several times.

If it still doesn't work, send it in for repair. MSD only charged me ~$40 to fix mine.

I think I may have figured out my issue.  I ran MSD's spark test and got a monster spark.  Then after noticing my ignition switched accessories, such as radio and everything else i wired up for switched 12v cut out while the starter is running, it seems that when i turn the key it shuts my MSD box off.  Fail.   :duh

Haven't tested it yet but it sounds plausible, and once again I am humbled.

While it has been "cold" outside I installed a one-piece headlight kit from LRS that my girlfriend gave me for Xmas and a bunch of goodies came in the mail today.

Pillar gauge housing for my wideband
Map pocket delete kit
Ash tray repair kit
Replacement rubber shift boot, OEM leather shift boot, and plastic shift boot shroud
   (old rubber let smoke in through the tunnel, old leather was bombed out and depleted, and the old plastic shroud had a switch hole drilled in it)

Most importantly, though:
20 feet of -6AN for my new return line and a 90 degree bulkhead fitting

The fitting didnt come with any sort of poly/nylon/rubber washers so i bought a handful of rubber and nylon washer options at the hardware store.  Will a OTS rubber washer leak at 7psi or should i buy some of these sexy little Earl's stat-o-seals?

As long as you mount it in the factory pickup, the washer will only see fumes and maybe some splash.

So, are these pickups worth anything to anyone?-  I am going to have to do some serious butchering with my Dremel to clear out enough real estate for the 9/16" hole and the 3/4" washer to seat squarely.  Maybe I am not imagining this right, but this pickup looks like it has the potential to find its way into my trash can!



Title: Re: 93 LX project
Post by: servo765 on January 03, 2013, 08:04:46 pm
Essentially looks like ill have to eliminate a chunk of the stamped metal brace that is tack welded to the top of the pickup, then grind the return line and anything else off flush at the top and drill the hole through.  God hates a coward so, what have i got to lose, but i dont know if anyone has a more graceful solution :thanx:


Title: Re: 93 LX project
Post by: juiced coupe on January 03, 2013, 08:10:04 pm
Yes, you will have to trim the bracket and offset the hole a little.

Its been years since I did it, but I was able to fit a 1/2" and 3/8" line and fittings in the stock pickup.


Title: Re: 93 LX project
Post by: servo765 on January 04, 2013, 12:16:04 am
After turning compressed air into sparks for an hour or so i got it on there.  I still have to cut up some rubber washers and select a flavor of sealant that tolerates gasoline, but it should work.


Title: Re: 93 LX project
Post by: servo765 on January 04, 2013, 12:18:30 am
And looking at the picture now, I supposed i ought to clear out the area underneath the discharge area of the fitting so it isnt spraying all over everything.

He's not running a external fuel pump, just a upgraded return line.

Besides, those pickup lines are hard on fuel pumps and cause them to flow less than rated. A sump is preferred.

Fuel pressure: working as advertised, set at 6.5 psi.

The car started and idled better than it did EFI both cold and at temperature!  Gone is the idle hunting and having to feather the pedal while cold.  It's the small victories.  It may never go down the road again but I am super excited right now!  I can't say whether it is running smoother or if its just the Energy Suspension poly motor mounts vs. the solids it had in it when i pulled the motor, but it doesnt lurch and vibrate at idle either.

I was fooling around with burping the coolant, and the timing is set at 10 deg BTDC at idle.  I was jazzed that all the gauges worked and there are no leaks.  It sat there right at 10 psi of oil pressure at idle and 185 degrees.  My new electric fan regulator is even working as advertised.  I was having a hard time resisting going around the block once, but figured against it since I have absolutely no clue what A/F Ratio I'm at.  I did shut it off and it wouldn't start back up immediately, the way it did cold.

I guess its time for some exhaustive reading on carb tuning!   :burnout

Thanks again for the support gentlemen!

Also, I think i've figured out what caused the ultimate demise of this shortblock.  I rigged a breather into one valve cover and a PCV into the other and with any RPM a barely discernible puff of smoke comes out the breather.  Rings I guess?  There was no proper PCV on it from previous owner, so when rings went, blowby blew out all the gaskets and seals that I originally pulled the motor for.

Good to hear the return line worked out.

Seeing that you only set the initial timing makes me assume that you have no way of setting the total timing. Either a dial back timing light, fully marked balancer, or timing tape. I prefer a marked balancer or tape, dial back lights can act funny with CD ignitions.

Unless you have changed the weights and springs in your distributor, you only have 31 of total timing at 10 initial and its not all in until ~4000 rpm. I would expect to see more like 35-36 total on a combo like that, and in as quick as possible. More initial timing will also make the engine more responsive.

If you don't still have them, here is a copy of your distributors instructions with timing graphs.

With the vacuum line plugged its seeing 10 deg at idle and 32 deg at 5000, all in by 3800 rpm

With the vac advance hooked up its over 40 deg at part throttle, 2k ish RPMs.  Is this too much on 93 octane?

I have it hooked to ported vacuum, btw.

Post by: servo765 on January 06, 2013, 11:47:45 am
About halfway down the page there is an intelligent sounding response saying at highway cruise you may see as high as 50 degrees advance but that still makes me nervous.

Post by: juiced coupe on January 06, 2013, 12:12:34 pm
That sounds normal. You will only see the vacuum advance under part throttle, low load driving.

If you want a adjustable vacuum canister, I believe a aftermarket one for a Chevy points distributor will work.

No, it's not, i usually have mine in the low 40s or thereabouts with mine at light load

So after setting idle mixture, idle speed, and timing I went for a joyride.  It ran better than ever for about 15 minutes and then started misfiring.  I was hoping it was going to be running well enough to meander down to a local welding shop to weld in a bung for my wideband, but I had to retreat home. 

I'm gonna pull some spark plugs and start doing detective work.  Based on the amount of smoke puffing out of the breather at higher RPMs I'm gonna go with a dual breather system to keep the motor from ingesting all the goodies in through the PCV.  In light of that, I also ordered a DIY 347 Liberator from Jim.  I'm super excited about that!

I changed out a set of plugs- the old ones had been in there since I bought the car.  I just went with 3924s @ .040 and I am gonna go beat on it for a minute and see how it does.  I also went with a double breather setup to keep it from breathing in all the blow-by and oil from my cancerous short block.

Since it has been raining and shitty for the last week and a half or so, I did a little work to the interior.  I was a little butthurt about all the dead batteries from the passenger sun visor so I put in new lamps and switches into those, and rewired everything that was owner added to a relay fed add-on fuse panel.

Does anyone have any experience with the $259.99 LRS window motor/door lock actuator kit?  It seems like i could save 80 bucks buying the parts a la carte from AutoPartsWarehouse unless its all junk.

Can yo u get a picture of the front with the hood closed? I want to see how those one piece lights look around the hood area. I have a pair of different style and they don't follow the hood line correctly.

Looks good though, all except that dinosaur contraption above the intake!  :spit:


Title: Re: 93 LX project
Post by: servo765 on January 21, 2013, 09:18:14 pm
hmm, these are the best ones i could find on my camera or take under the lights.  In the close up one you can kinda see in the upper left corner where the light doesn't perfectly chase the lines of the hood, but its a fiberglass cowl, so who knows which lines are more correct.  If you are considering this exact pair I'd be happy to remount the OEM 3-piece set for comparison's sake.

http://www.latemodelrestoration.com/item/SDT-13007B/1987-93-Mustang-Black-One-Piece-Headlight-Pair

You have to be on your hands and knees to see the shapes don't match perfectly.  While standing they look great as you can see in the other pic.  This pair didn't come with the cut-to-fit weatherstripping or propensity to leak like a similar pair my cousin mounted on his vert.

Post by: servo765 on January 22, 2013, 08:16:21 pm
Seriously...The one piece design seems like a no brainer to me, I just wish the lens was textured like the OEM style instead of clear "euro" style.

My next issue for the think tank...

My car starts immediately while cold, runs great, but if you shut it off or stall it, you're gonna wait 20 minutes to restart it.  I chased around fuel/carb issues first, but have narrowed it down to ignition.  When it's in one of its moods, grounding the mag pickup wire will not throw a spark, nor will turning it over with the key cause a timing light to blink.  Give it a breather and the above two tests function fine, and the car starts.

Setup:
antique Craigslist 6AL
Brand new MSD Blaster 2 coil
Brand new MSD Pro Billet Vac Advance Distributor
Brand new MSD Street Fire wires (7/8 anyway, oops)
10 degrees initial timing
Coil and 6AL mounted passenger side, forward of the shock tower

Blaster 2 measures:
0.6-1.0 ohms across the +/- terminals (spec is 0.7) (shitty multimeter.  did i do this right?)
5.4k from negative to the top (spec is 4.7k)

Question 1)  Are those specs far enough out to question the coil?
Question 1.A)  Would you pay $76ish+ shipping to MSD to repair an ancient 6AL, order up a new Digital 6-Plus for 299.99, or order a Programmable 6 for 316.79?  "Or maybe something really cool that I don't even know about?"


Random troubleshooting follows:

fuel pressure is good (6.5 psi)
tank-to-reg lines are cool, reg-to-carb lines are not hot
no obvious signs of fuel boiling, no fuel running into primaries
pump shot looks to be the same volume
starter cranks over without laboring
starting fluid has no effect
battery voltage has no effect
choke position has no effect
it does not even "try" it just turns over and over
Scenarios:
If the entire thing is cold i can start it/shut it down at will.  If i run it for 20 miles, pull in the drive way, shut it off and immediately try a restart it will not start.  If i then go inside and have a beer or two, come back out it will start right up, but if i then shut it off and try a restart all in the span of 30 seconds it will not.

Thanks for reading!

Post by: HIGHVOLTJ on January 23, 2013, 01:47:58 pm
I've had an MSD do the same to me, last part I bought from them.  Try swapping it out for something else (like a stock duraspark if you have one) and see if it still does it.

This was what I used to diagnose my ignition problem.

Did MSD go up on their repair prices? Last year, they told me that the max repair price on a 6AL was $50. Ship it parcel post for just a few dollars.


Title: Re: 93 LX project
Post by: servo765 on January 23, 2013, 04:29:49 pm
Ya I called their tech line this morning.  Its actually $87 max.  The idea of having spent 200-250 bucks on an old 6AL irritates me, so I am looking real hard at the 6-Plus and Programmable 6.  Lotta capability for 316 shipped.  Whether I'd ever use it all is a question for another day but it seems to me most people don't want to go slower with time.

The tech didnt suspect the coil to be bad, he said when they fail they usually go way high on resistance, not just a 10-15% jump.  I guess having a spare ignition controller wouldnt be bad to have lying around anyway.  The piece i don't understand is the dwell.  Do I need to limit my vac/mech advance or anything?  NAPA has a GM Control Module for like 27 bucks I may try out.

No. At the time, my distributor was locked out. Full timing, all the time. I just needed enough mechanical advance to start it. So I just set my advance up to provide ~10 of advance, all in at idle. So its basically just a mechanical start retard.


Title: Re: 93 LX project
Post by: juiced coupe on January 23, 2013, 06:20:40 pm
First off, I don't think its an ignition issue. Sounds like the carb is getting heat soaked. Seen them get go hot that you couldn't hold your hand on them. My car has never been without some type of thermal insulating spacer on it.

I sent by box back to MSD this past March. It was so bad that the car would barely run. I just checked the ticket, it was $31 for repairs and $10 for return shipping.


Title: Re: 93 LX project
Post by: servo765 on January 23, 2013, 08:44:20 pm
Well, won't be the first or last time I was wrong-  I'll order a spacer, but my mind is expanding at the moment. 

I would have thought the inability to fire the coil with a jumper wire whenever it gets hot would have been the smoking gun. :hmmmm:

Check the plugin connections for the magnetic pickup. I have seen them loosen up and cause erratic problems.

Post by: Cold Aussie on January 23, 2013, 09:28:28 pm
It is definetly coil related! If it was fuel surely the engine would attempt to start on the starting fluid.
You say you have 7/8 new leads, is the coil lead the odd one out?


Title: Re: 93 LX project
Post by: servo765 on January 23, 2013, 11:32:16 pm
Haha no I guess I should have written 8/9.  I roasted the #4 plug wire on the header and have one junk one on there.  I do like the cheaper wire's 45 deg plug boots a lot better though.

I made up a JuicedCoupe brand 6A and the car started and ran well but thats as far as my diagnosis made it tonight.  As I was pulling back into my driveway to attempt a home-terf hot engine start my neighbor's son came to the door so I figured it was time to call it quits.

Also, yesterday I had a local exhaust guy weld in an 18mm? bung for my WBO2.  Things are coming along one project at a time.  Some days I move closer to the goal and some days farther but I'll get there.

As always I appreciate the input!

I installed my wideband this morning.  Turns out I haven't done enough research to be able to interpret it, so it wasn't the tuning epiphany I somehow thought it was gonna be.  I have a part throttle misfire which causes my A/F Ratio to show mega-lean.  I am gonna check vacuum leaks and throw a vacuum gauge on and see where I stand vacuum wise.  My brakes get real mushy after being at idle for a bit (car has always done this) so I wonder if my weak vacuum is causing some power valve issues. 

Also, an interesting coincidence.  My driver's side window motor finally bit the dust so I emailed LRS about their window motor/door lock actuator kit with some part numbers from various other websites trying to figure out why their "combo kit" was 80-90 bucks over priced.  Two days later the kit came down 50 bucks in price, so I grabbed one of those and that's my project for today.

Also, quick question:  when pulling the intake manifold off, after draining the coolant, is there a graceful way to keep the remaining coolant out of the lifter valley?  Or does it not pose a concern?


Title: Re: 93 LX project
Post by: servo765 on February 06, 2013, 10:51:47 pm
So at idle my car is pulling 11 ish inches of vacuum, which according to holley's tech means I should drop down a size in power valve from a 6.5.  I am going to do that just for my own curiosity to see if it helps my part throttle misfire issues.  I am curious to see what this set of plugs looks like though, as this misfire didnt crop up immediately so I suspect the plugs have been soiled a bit and the power valve change wont do much for me.  I figure if the 6.5 was too high, i would see the wideband go overly rich from opening too soon until the misfiring began at which point it would show lean were the power valve the actual issue.

The breathers are belching out what I would consider "a lot of smoke" even at idle now so I am glad my 347 is going under the knife at Fordstrokers soon.

I am also beginning to flesh out a final build sheet that I will be posting up soon for critiques and some much needed advice.  My short is paid in full and a deposit is down on the heads.  Getting excited!


Title: Re: 93 LX project
Post by: juiced coupe on February 07, 2013, 01:04:27 am
You can try, but I'd bet that you wind up back with the 6.5" PV. You likely need to tune other aspects of the carb and engine.

For what ever reason (probably tight wads corporate Holley not paying their tech enough to attract ones who know their ass from a hole in the ground) Holley tech is so far behind in the truth and the times ... Holley says your PV should be half of your idle vacuum reading and I've found personally that is a load of horseshit!

If at idle you are getting a solid verified 11" of vacuum then that is far enough away from a 6.5" PV that it will never open when it's not supposed to as long as it is not defective.

My 408W has 6-7" of vacuum at idle and it's 4.5" PV works fine opening only when I get wild with the gas pedal under a load of the road.

I've found that making my A/F mixture screws a little bit richer (as in adjust only one screw 1/4" CCW -- and yes they all do NOT need to be adjusted the same amount as long as you are not using a DP manifold that completely separates the cylinders!) helps with part throttle lean issues.  If you are having that lean of a condition you MIGHT want to also look into enriching your primary jets 2 sizes up ...


Title: Re: 93 LX project
Post by: HIGHVOLTJ on February 14, 2013, 06:04:49 pm
Yeah, that doesn't sound right at all.  2" below your lowest cruise vacuum is what I've always used for power valve rating.

Although I'm rusty at this carb stuff, it's been a while.  Trying to find my damn Holley tuning book right now actually!

well, for what its worth, everything I know about tuning carbs came from the 'super tuning and modifying holley carburetors' book by Dave Emmanuel.  I am in the trial and error phase right now, and getting real familiar with changing out spark plugs.

Using a fixed vacuum below cruise vacuum makes a hell of a lot more sense to me than 'half your idle vacuum' based on what the PV is supposed to do though.

Yeah, (same book I have) You don't want the power valve open unless you are accelerating.  Some people do weird shit where they run lean jets and a larger power valve, or richer jets and a very low rating power valve, but not for me.

Well,

     I closed out the balance on my DIY 347 and TW205s today, and its supposed to ship tomorrow.  I am so excited!  Anyway, I have a handful of questions, particularly regarding valvetrain to purchase, as well as engine building tools that I will be posting shortly after i watch the rest of the sbfbuilding videos and troll some forums- I currently don't even know what I do not know so I gotta get smart on some of that stuff first.

My mic and bore gauge arrived last week, so I pulled open all my goodies and started taking measurements and doing pre-assembly steps.  So far so good on that front.

I have been rubbing machined surfaces with WD-40 every few days since I opened up the boxes, and have rubbed a fine coat of ATF in the bores, but they all look spotless.

However, I stumbled across a pencil-point sized area of spot rust on the #1 main journal while mic'ing the crank.  If I drag the pad of my finger over it I can barely feel that its there, and if I use my left hand I can't feel it at all due to calluses from playing guitar, if that gives any indication to the severity.  I did some searching and someone suggested wet sanding with 2000 grit sandpaper and then finishing with a polishing cream using a 'shoe-polishing method' with a strop.

Does this sound reasonable?  Or does this need to go out for polishing?

It has been a long time since I have posted.  I had some things come up which re-aligned my priorities in my personal life, but I am cleaning my garage and prepping it for surgery again.  Time to start moving forward again on my DIY 347 with renewed vigor!

I look forward to browsing the forums again and badgering the thinktank with questions.

Happy Thanksgiving everyone!

I have picked up my 347 project and this time have some momentum going.  I made it through pre-assembly, finished up the short, and started installing my cam and timing set.

How hard are the cam dowel pins to insert?  I tried tapping mine in and didnt know how hard to whale on it.  I pulled it back out, chucked it into my drill press, and rounded the leading edge real well, and it still wont go in.  I was going to get a BFH out and force it in there, but online videos show people just inserting them with their fingers.

the cam in question is a Comp Cams custom grind on a billet core.

thanks!

Got my heads mocked up this morning.  It ended up liking 6.800 (8.2 deck/"old" style Trick Flow 205s) using a converted stock lifter.  That leaves me with 6.750 pushrods to accomodate the Morel linkbar lifters.  I also need to clearance the back of the rockers ("new" style Ultra Gold 1.6s) since the pushrods are either binding or very close.  Roll-out pattern in the marker on the top of the valves was larger than I expected at .055ish

I am closing in on the finish line!

Can anyone recommend a clutch and flywheel?  Tremec 3550, street car, hoping to be in the 450-475 hp range when its up and running.  I am unable to reuse any of my old stuff since it is all at 50oz.  Not sure if i need to make the jump to a billet/SFI flywheel and so on.  Kind of eyeballing the Ford Performance billet flywheel at $235.  No idea where to land for clutches.

Nice, well organized shop.

And I thought my OCD was bad.  ;D

haha, I tell myself it makes it easier to pack-move-unpack since I move every 2-3 years, but I'm pretty sure that's just rationalizing.  The white paint does keep crappy rental garages a little brighter though.

Happy New Years to everyone!

I am traveling for work until tomorrow... but... Bolt the hood back on, prime the oil system, stab the distributor, set float levels, and turn the key!   :rock Considering I bought the DIY 347 from Woody almost four years ago, it will be nice to have my car on the road again.

I picked the project up in earnest in October and started over from square one with mic'ing the crank.  It took me four months of nights and weekends to do what I assume people do in a long weekend, but some projects go like that.  I didnt cut any corners with pre-assembly or assembly that I know of and got a hell of an education from SBFBuilding.

FS DIY 347
Stock Roller Block
Scat cast 3.400 crank @28 oz
Scat 5.400 I beams
4.030 Probe SRS pistons
Custom Woody Cam
Woody's TFS Twisted Wedge 205s
1.6 Ultra Golds
Morel Link Bars
OOTB RPM Air Gap
ProSystems 780cfm 4150
7qt Moroso pan
Powerbond balancer
SA Gear timing set w/ bearing
MSD Billet Vac/Mech Advance, 6AL
BBK Shorties to 2.5" exhaust ( :duh )
FRPP Billet Flywheel/10.4" Centerforce DF Clutch
Tremec 3550
4.10 gears
LX Foxbody, full street trim.

It's kind of a cookie cutter build, but it should be an absolute riot for a street car.  Four years ago I wanted to go as fast as possible.  Now I just hope it doesn't grenade during break-in and hope it lasts long enough for me to work through the small stuff, get the suspension right, and have some fun.

*Desperately needs longtubes and 3" exhaust but I am out of money for now.  In my perfect world, I put the longtubes in while installing a Team Z front kit.

1. Anybody have a decent set of headers and X/H pipe for sale?
2. Can anyone point me toward a link or some advice for making A/C work after a carb swap?  If that is a bridge too far, I will re-work my accessories and shed a few more pounds, and then just kill myself in May.
