I'm looking for a cam for my stock '68 383.
I am adding a 4 bbl and dual exhaust with H.P. manifolds.
otherwise it's stock.
Going back into my New port.


Based on that info, I take it this was originally a 2bbl motor.
If that's the case, than a valve spring upgrade will be required for virtually any cam swap.

Personally, for that application I feel the smaller summit cam would work just fine, along with a set of stock replacement hp springs.
Swap out the valve seals while you're in there.
