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

I tried them before. I'd avoid them.

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.

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.
