Want Help Adding a cam to 1968 stock 302
I want some expert advice on adding a cam. I have a 1968 stock 302 motor with the Edelbrock RPM Performer intake and holley 600 CFM carb.
Code on the engine is C8OE.
The car is a 3 speed with 9 inch rear end (don't know the gearing on that yet)
I was told two different things;
Machine shop said to keep the cam at about 216 and 474 lift and not to go over that amount on lift. Kinda makes sense.
Mustang shop said to match the cam to the intake manifold, which sounds kinda okay at first.
The rpm performer cam spec is at 224/234 intake and exhaust duration
and 496/520 lift. Both numbers seem way over the specs suggested by the machine shop.
Also the specs for this cam at summit say it requires valve springs. If I have to get new valve springs how do I know what to get and how do i measure what I have and also will the increased strength valve springs be too much load for my stock heads??
I prefer to keep it simple but I want a cam that will sound good at idle and mild-moderately increase torque/hp in low to midrange.
