hey all I am new to this fourm but this thread here is why I join mostly.
I have a amc 401 with about 10.5:1 to 11.0:1 comp ratio( the reason I don't know excatly is because I bought the engine as a "whole") but the highest octane I can get around my parts is 94. Do you think I could get away with this? I also have stock cast iron heads but there ported right out.
any info would be great thanks justin
