I recentlt bought a nice 92 f-150 302 4x4 ex cab.Motor works good but has bad crack in exh. manifold.i want to build thisengine to 325-350 hp.want it to handle the occasional mud hole.I just put 33 hercules mud tires on
1.i just bought some hedman long tube headers and a 2 1/2 pipe kit with no cats and two c.b. glasspacks.
2.I have a f303 cam in my garage barely used
what parts should i be looking at?Ive been told not to run that cam without switching from speed density to mass air first
if i dont switch what cam/heads(cant find gt40p's)/intake should i use with the exhaust
if i use the cam is it now going to NOT be so much of a budjet build or does it work out the same in the end.
would it be easier to i find an 87-93 mustang motor complete with computer?i would prefer not to do that.
Any assistance would be GREATLY APRECIATED!
I dont know what to do but i am ready to roll on something.
Get some flat top pistons & a mild cam. If you get too wild, you'll need a special tune. There's alot more going through that ECM than just the engine controls. That's just my opinion.
The long tubes & exhaust will help alot , i don't think you can use the f cam with out mass air , check craigs list for some gt-40 heads , what gears are you running with the 33s.....

Ive been told the same about the cam,Maybe someone can confirm for us that the truck wont like that cam.
Im in Moncton New Brunswick Canada.We dont have C.L. but we do have KIJIJI and i monitor it like a mad scientist
Chris these trucks came with a wild range of gearing options so "stock gearing" literally means nothing. It really doesn't matter what gears are in it now though because you need 4.56's for those tires and that ratio was never offered. So start with that before you do anything else because mods to the 302 will make the powerband even peakier than it is now so you need to get the truck setup to let the engine spool. Your transmission will last much longer too. None of the Ford alphabet cams are compatable with the truck SD EFI system so it needs to be conversion to mass air first. Once there you could use the F cam but it's all wrong for a heavy truck IMO there are much better options out there that will produce a wider powerband.

Came across couple articles on subject. Also recall reading article in CarCraft, not sure what issue; if interested, may be able to locate in their online 'tech' section. Ended up taking the 302 to shop and found the articles helpfull, was not at a total loss in letting them know what I wanted. Anyhow, not sure if any help, if nothing else may make for interesting reading.

thanks conanski/chemicalburn,more like this.keep it coming.put the long tubes/2 1/2 pipe kit/glasspacks on yesterday
You could try out the cam I have in my 5.0.. comp 35-349-8, it certainly make lots more power than the stock cam.. approaching 300hp. The heads are fine, save up you $$ for the gear swap.

The f303?Even with the speed density?Alot of work if the truck doesnt like the cam and i have to remove it dont you think?
No not the F cam.. as already stated it's not compatable with your EFI system. I suggest you try the Comp cam I have in my 5.0.
