Sb388
I am buying a 388 sb to put in a 67 chevelle an it is about a 680hp motor an it is 12 to 1 compression that is to much for pump gas , can I change cams and detune engine with smaller cam an put a thicker head gasket on it an get compression down enough to run on street with pump gas.
Is it going into a build, or making a trip to NM?
