cam questions

[Applejaxx95vert]

I will be getting a set of gt40p heads, I currently have an x cam in it. With that being said it also has an explorer intake bigger throttle body and stuff. What cam would be the best for what im doing now?

x cam be ok but need springs on the heads

X2 change the springs to match the cam, port the lower intake, have the heads machined for 3/8 studs for rr use.

The X cam is not at all right for that combo. I think the heads stop flowing at .500", so what good is a cam with .542 lift? In any case it's not going to be well matched to the combo. If you had to have a motorsport cam, I'd sell the X and buy an E.

Quick search brought up this...

The 2031 cam profile was designed for the GT40 head. Reason I know this, is when I rebuilt my old 92 LX that had a Cobra Top End I wanted a cam that would match the heads that I had sent out to be ported.

After researching cams, I called Crane and was told the best cam for the 1993-1995 Cobra was the Powermax 2031.

The cam is a proven cam.

I to have been told that anything larger then .500 lift on gt40s is too much. Im running an ecam with my setup. I think there is a ecam with low miles for sale in the valvetrain section.

a b303 cam with 1.7 rockers or a steeda #18 will make the most power due to the added duration. I had pheads,b303cam, stock shortblock, cobra intake, full exhaust, pulleys, tbody, 24lb inj, c&l maf and bbk cai my car made 275/316 if i remember correctly and that was with stock rockers id say i wouldve been closer to the 285-290 mark with 1.7s
