I have a 1987 F-150 EFI 302 Speed Density and im looking for an aftermarket cam but it is difficult since these truck are hyd. flat tappet. I need at least a .450 lift cam to make it hit kinda hard. It would be very helpful if you guys could help me find a cam.

 

That's easy, comp cams 31-255-5.

 

thanks so much man it helped alot

 

conanski, i was wondering IYO what would be the best cam for a 90 f250 4x4 5-speed 3.55g, that i tow with. i dont want to change the gears but i want more low end, i dont drive fast but i want lots of grunt. alredy have headers and free flow exhaust. when i do the cam ill probably do the intake and maybe a mild port to the heads.

 

What motor? If it's the 351 I suggest the Crane 444232 and don't change the intake just port the lower to match the heads.

 

sorry its a 351w. im not real advanced as far as motor building so what do you mean port the lower to match the heads? do you mean to port the lower intake manifold to match the heads intake?

 

yepp thats what he means
