For us, in a Stock 427/425, and a Super Stock 396/375, Sonoco was slower, down about 10 on HP, than C12, and I made the most power on C14+.


The main cimplaint with C12 is that it sometimes didn't pass fuel check, even from a fresh, just opened VP drum on their trailer. NHRA would always "adjust", however it was a hassle, and sometimes they wouldn't re-instate a qualifying shot.


A lower compression and/or smaller engine might not care.
