camshaft for mild 340

I know that there is more than one car that runs 11's with that dinky 214/224 cam, stock rockers, in 360's with well ported J style heads and a great chassis.

.904 or not, you can make good power and be easy on parts with any number of combinations. Not everything has to be used to the optimal level.

Key word in the OP... MILD!!!!

Make what you got work. There are good grinds out there, choose one and go with it.
