Tried and true, and easy on the valvetrain....
Comp 260........
ISKY260......
The Hughes cam has too much lift for the stock springs and heads.
Hughes will also trying to sell you a cam with a longer EX duration for small port heads, no reason to have it, unless you like giving up low end torque for a couple hundred RPM up top. (not advisable in a 318 power truck)
If your looking for lope, have ISKY narrow the lobe sep to 106 or 104. They grind me cams all the time like that, for 150-175$. Remember, a motor that has power sounds a hell of a lot better than a motor you're trying to make sound like it has power.
