The intellectual post,about old school camshafts,the newer ramp cams.. and what's needed ,in modifi

Allways but allways get the best/most cylinder head you afford dollar wise and for the engine at hand.

Build power with a cam. I never thought that way. Cam is 2 things to me. On the simple.

Lift = How much air it is allowing the engine to breath in. Hence, that wonderful word again, HEADS! And everything above it and attached to it.
Breath in, breath out peoples.

There really is no reason to over think it.
