Can any one please give me some advice? I have a 79 f100 with a 351w stock heads edelbrock intake with a 650cfm holly, headers and a posi with a 3:50gear i have been looking for a performance cam but i don't know what will be good. I want the sound and the extra power. I will really appreciate the help. thanks!
I'd go one step(or even two) down from Larry's recommendation due to the weight of a truck with only moderate gearing and likely having a stock stall convertor. You SHOULD be wanting low-midrange torque without much care for a near 6,000 rpm redline because that small volume manifold is all done by a little past 5,000 rpm anyways. The motor will feel bigger and more responsive to the pedal without having to rev it to get all that weight moving. Better mileage too.
