UPDATE: Its alive!!!


After months of heat and rain, it finally started today. After a few problems(stuck needle/seat with gasoline geyser followed by carb fire and some dumb ass got a couple plug wires crossed), I have to say in made my day to hear it run.

I was also happy to see that it never got above 150* while running it for a half hour or so.

I would also like to say thanks to Jay for the way this thing revs. A quick blip of the throttle and its all over the rev limiter(7200). You were also dead on about the idle, its nasty and doesn't like anything lower than 900.

Anyway, I still need to get the exhaust on and fix a few small problems before I can take it down the road, so back to work.

Almost the same combo as mine!! HAve you tested it yet?  Any Numbers??

[juiced coupe]

Sorry, no numbers yet. Still working out some kinks. Got a few problems and its too close to Christmas(4 kids=$$$$) to be blowing alot of money on the car. Anyway, here is a quick update.

Got the exhaust on. Sounds great and I can hear myself think again. I modified a shorty H-pipe and ran back to a set of Pypes M-80 mufflers with dumps at the rear. I just need to seal up a couple slip fit tubes on the headers.

I have also been doing some work with the carb. After replacing a sunk float and playing with float levels and squirters, the carb seems to be doing ok. I just need to work on a little stumble with the secondary transition.

Now for the problems. This thing is VERY cold natured. Hell, my chainsaw and 2 cycle ATV crank better than this thing when cold. It also has an intermittent stumble that I cant trace down. After alot of thinking(do you smell smoke?), it may be possible that the problems are linked. I think that my homemaid shimmed lifters(stock, who knows how many miles) may be fubar. My adjustment of said lifters has also came to mind. After reading some of Jays comments about lifter problems and valve adjustment, my theory about the lifters seems valid. I have to pull the intake manifold anyway(oil leak at back), so I plan on changing the lifters while I am there. My plan is to get with Jay after the holidays and get a set of Comp 851s or a set of HIS shimmed lifters, whichever he thinks best.

Until then, I have several small projects to keep me busy. I need to install my subframe connectors, driveshaft loop, new headlights, and work on some wiring problems(fun).

Maybe I can make it back to the track by spring.

[survivalstangsnj]

I am having the same stumble problem.  Im going to be changing squirters and messing with timing.  I have brand new lifters so im not worried, but if it continues, I am!!

How does the M-80s sound?

[juiced coupe]

The M-80s sound great. They have a loud but smooth sound, similar to a Magniflow. That makes sense because they are both straight through, preforated core designs.

UPDATE:

Looks like I got my carb issues fixed. After chasing my tail for a while, I decided to open up the carb and compare it to the specs on Holleys web.

The jets weren't what I thought they were(67/76 and I don't remember why), so I changed them to 73/80. It starts and drives around much better.

I tried several different squirters and found that it liked a #31 on the primary, but would still go dead rich(flutter, black smoke) when the secondaries came in fast. Even with a #25. Decided to check the pump cams, both were pink/#1 hole. After a few different cams and positions, ended up with both having orange/#2 hole.

I also got some clear sight plugs and raised the fuel levels a little. The level was at the bottom of the hole, I raised it to about half the sight plug. Seems to have helped a little all around.

While on a test drive, I realized something else. I need tires worse than I thought. With the stumble gone, it doesn't just spin, it incinerates the tires. I nearly lost it from a 10 mph roll.

I still have several other things that need to be done. If the weather will stay clear, I might get a chance.

FUCK, FUCK, FUCK.................!!!!!


Thanks to the coldest winter in over 25 years, I have to pull my engine back out. 2 core plugs on the ground and 2 more half way out.

I was in a stretch of 7 night shifts when the cold weather hit. I thought (yea, that's what I get) it would be safe to just pull the lower hose and drain most of it. I figured that if any of the remaining water froze, it would just expand upwards. NOPE!

So, I'm going to look at it like this. I needed to pull my headers to fix a couple leaks anyway. By the time I'm that far in, it would only take about 20 more min to pull the engine. An extra hour and $40 in parts and fluids, it could be worse(I hope that's it).

Finished putting it back together today.

1- New core plugs in. No leaks!
2- New Comp lifters in, also fixed oil leak at back of manifold.
3- Fixed leaks on the slip fit tubes on my headers.
4- Built/installed header evac system the way I wanted it(line to one valve cover with a "T" under the car). Didn't hook up gauge, but I can feel vacuum at the dipstick tube.
5- Installed drive shaft loop and full length subframe connectors(MM).
6- Ran/fixed some wiring on the car. Ran the NNS to a relay near the starter(works good and the car cranks better). Installed new coils on the nitrous/fuel solenoids and ran better wiring to them.
7- Also changed a few things on the carb(jets, squirter)

The weather was cool this evening (mid 50s), so I decided to go for a little drive. Drove to a couple friends houses and left the car running while we talked. No cooling problems or issues with the carb loading up. I also put about a 25% mixture of anti-freeze in this time (instead of just water) and the car seems to like it as it is running about 10* cooler than it was before. About time to get some tires and go have fun.

Can you hook a vacuum gauge to it? I have wondered if that wouldn't work just aswell.

Thanks

I would not just run water as a coolant.

[juiced coupe]

I plan on hooking up a gauge when I get a chance. I didn't have the correct size reducer for my vacuum gauge and didn't feel like going to the store again.


On most of my high performance cars, I normally run water with just some Water Wetter in it. It rarely gets that cold down here. Also, anti freeze is very slick and hard to get off the track if something happens(overheat, blown hose, etc). Stock / mild cars are less likely to have these problems.

Water and some Water Wetter keeps the rust and other bad crap that goes on in your coolant system from happening?  How much Water Wetter do you mix with just water?

[juiced coupe]

I use one bottle per cooling system fill.
