so how does this work? do you drill out the pully to accept this to get timing where you need it?

found this one, seems there just isn't much out there for 4x4 trucks, seems to be mainly for high rpm with big stall converters.....

For a 351 truck, the stock Mustang or Thunderbird HO cams are good choices, especially considering that you already have 1.7 rockers.

If you want a OTS cam, I'm a fan of this one for factory head engines.

I tried them before. I'd avoid them.

I looked around and still have the kit and modified gear. You can see how much the gear had to be drilled out for the bushings to fit. I had this done by a machine shop (many, many years ago), and the bushings were still a very tight fit.

Its one of several things that I keep around as a reminder not to be cheap.

wow...thanks juiced.

i just hope that cam i have really is a 5o ho cam and not something else.....is there a way to tell?
or is it one of those im going to have to install and degree every lobe? half the lobes look the same but the other half are way the f off from the eye.....

looks like i'll just do a basic rebuild/rings and gaskets and use what i have for now.......then i can do the other engine properly as i go and budget allows.

I'd just use a dial indicator to check the lobe lift.

The regular HO cam should have. 278" lobe lift on the intake and exhaust. There are a few variations throughout the years.

The 93 Thunderbird HO and 93-95 Cobra cam should be. 282" on the intake and exhaust. Even though this cam has slightly more lift, it is a little milder than the regular HO.

I say should because I've never checked a cam that was the same as rated specs. Some are close, while others are completely screwed.

All of the base cams should have a noticeably higher exhaust lift.

that cam you mentioned, will it need pushrods and springs?
been trying to find videos on cam degreeing, looks like i need a subscription to woodys vids, those seem pretty nice.

Springs? Different than stock? Definitely.

Based on your other thread, it looks like you are using heads that have been upgraded.

So, different than what's on them? Maybe.

Pushrods? Maybe.

Do your heads still use pedestal rockers, opposed to studs and guide plates? When the valve size was changed, did they use ones the same length as stock?

its been so long ago when i installed them, im almost positive they were studded. i think they had the chevy 190 intake valves, double valve springs, don't know seat pressure, i could barely move one with all my weight on top of it, not like the weak stockers that i just hit with a socket and hammer to remove them. i remember getting them real cheap with a bunch of other stock stuff like fms headers and that cam. it was suppose to be a whole swap over but i never put the cam in.

i have not pulled them yet off of the old engine, that thing knocked for about 5 years before it finally got too bad to run anymore....lol. they don't have many miles on them, maybe around 7500 or so since i put them on. never noticed any performance gains with them.....none at all, what so ever, not in the slightest. the maf conversion and edelbrock uppper/lower were the most noticeable power increase i could actually feel.
come to think of it, i think i actually lost bottom end torque. i bet they would be good under more compression.

Guide plates require hardened pushrods.

Standard SBC valves are shorter than most sbf valves.


The best thing to do with the valve springs is check them out, or have a machine shop check them. I'd check installed height, seat pressure, pressure at 0.500", and coil bind.

well from what i can see, as well as a lot of pics on the net, the 5.0 cam i got is not the same firing order. the lobes are way off as well as the sprocket pin is shorter as well.

about ready to do some cam degreeing with the stock 96 roller 351
just so im on the right page.....

could i put the crank in and just the number 1 piston/rod for tdc
and put cam in, timing chain/sprockets, and one hydrollic roller lifter with the dog bones and spider tray to hold them down and check cam lift and duration from the lifter?

what can i use in substitute for the lifter? i mean would a 3" extension or socket or anything that is solid that the dial indicator could ride on be better?

Your basic method is right, but be sure to do both intake and exhaust to verify the cam is correct.

You will need to use a roller lifter--a none roller device will ride the lobes differently and you won't even be close to being accurate.  It doesn't have to be the exact roller lifter but its best if it is the same as what you are going to run.  Use the dog bones too because if the lifter gets cocked in the bore, it can gouge the cam.

Single factory type roller lifters are cheap.  You can get a couple and make them solid.

i was thinking of using something else just because my dial indicator is what im not sure will ride on the lifter where the pushrod meets, but i guess i could put the dial indicator on the pushrod tip but it will have to be almost perfectly vertical.....i don't have a spare right now to make a solid.....how would you make one solid? just buy a single solid lifter?

since i have dial indicator extensions, is there any way to put it directly on the cam itself? like stick it down the lifter bore right on the cam lobe? yes i was going to do both intake and exhaust.

the only problem i see is that it may push the dial indicator extension to the side too much giving a false reading. i guess i could just stick it on the top of the lifter, the indicator does not have that much resistance.....thanks
