Most cams seem to support efficient operation over about a 1500rpm range so the question becomes where do you want to make your power?

I think this range can be moved about 500rpm going from stock 930, to SC to C2 and a little bit more if you play with the timing of the cam you choose. With every cam the effective compression ratio the cam makes goes down and this can effect your off idle pre-boost power some (say 1000 to 2000rpm boost onset).


For your drive-ability goals it is hard to beat an SC cam which is why it has been the go to cam for so long.

Might be best to find a used one in excellent condition and have Elgin, Web, or The Cam Grinder install a drive block on it for the turbo savaging pump. This way you get a factory hardened cam with full diameter lobes that keeps the rockers at the correct angle to the cam. New rockers or rebuilt so as to retain the stock geometry is a good idea. You need to reset your spring heights or go to proper sport valve springs.

I suspect a custom cam if it has to stay in the rpm limit of stock rod bolts , CIS and or be smogable if needed is not going to show much improvement on a stock displacement 930 over an SC or C2 cam.

Not an expert.
