302 to much cam?
A friend of mine had a 302 rebuilt about two years ago for his 85 stang. He has about $3000 in the engine. I can pick this up for my 76 EB for $1500 he's having some money problems. The engine wasn't ever started, sitting in the garage the whole time. The only thing that bothers me is the cam, it's the Ford Racing X-303. I have a auto transmission and believe it's to much cam for the Bronco. If you guys think its to much could you help me with a cam? Maybe an RV type of something... Block is 30 over, 10-1 pistons, Heads were set up better than the GT-40's, RPM manifold, etc... Dan

Your right too much cam. IMO your best bet would be to give comp cams a call 1-800-999-0853 tell them whether your running efi or not and they will ask you to give them all the information about the engine and the rest of the drive train, then they will ask you what its used primarily for.....then give you an idea of what you need. They will more likely than not recommend you an extreme energy camshaft, seems for a few reasons they are about the best going at the moment. I have spoke with many who have used them and they seem happy, not to mention a few custom cam makers I spoke with liked those better than other options (brands and grinds) they were given to consider. Who knows? With that compression ratio I think you will need something other than an RV camshaft, which is designed to build cylinder pressure in low compression engines, you may need to go to something up the grind list to help alleviate cylinder pressure so you don't have predetenation problems. Thats my opinion though...Good luck and let us know what you end up doing, sounds like a nice project

Depends on what you use your truck for. That engine will make good power at slightly elevated levels but not too high. With a stall of about 2200 -2500 it would be a powerful mudding engine or such. For a daily driver it would run too hot and use too much gas. That engine would work well with the stock mustang HO cam and work good with the stock converter in your truck and get pretty decent milage and bottom end torque. Good used HO cams can be had cheap (check e-bay) and the lifters will work without any problems. the 10-1 compression will require premium fuel unfortunatly.
just my two cents

Thanks, gas milage is the least of my concerns. I always run premium fuel in all my vehicles anyway. Its not my only ride, but I want to be able to drive it wherever I want to.
jwtaylor.... I called comp cams today and sat on hold for about a half hour. I will call again just ran out of time today. That cam isn't that rough at idle.. I had the same cam in my 93 Cobra. But I do think its wrong for the Bronco. I guess I'll find out from them.... I will need low end power. It's going to be a trail rig/something to putt around in.

Just a thought. I have heard that using a stock ho cam is a good option for roller motors, I even read were someone pointed out that a well known custom cam grinder, made the comment that the 302 ho camshaft was a good option for a street vehicle. With that in mind I contacted the cam grinder myself and he said he said no such thing and wouldn't recommend any stock camshaft. Does that mean anything? Couldn't say, but just thought I would share my experience.
The comp extreme energy camshafts are all about low end torque and increased manifold vacuum. Good luck

Yeah, I agree with jwtaylor. I just installed a comp extreme energy cam in my 302. I was very pleased with the results. It is the 272 grind, fair idle and explosive power. It did leave me a little mushy on my bottom end. So I pulled the 3.25 gear and installed a 3.70LS and a 2400 stall converter. It nearly boils the tires off the rims now.
