Just did a compression test on my topend and got 163-165psi per cylinder. This is with vito's superstocks (I know they drop compression some) and 19cc domes. Oh, and the porting. Elevation is around 500-700ft, so all this sounds good since the topend only has around 3 hours. I've ran 110 octane C12 for the break in, but it's around $7.75 /gal locally. I can buy leaded 111 at a gas station for $5.69, and I can also get 100LL av gas for around $4.25 /gal. Just wanting opinions on what is best for my compression without breaking the bank and what mixes together if I can get by doing it. If anybody knows anything about the 100 octane low lead av gas it would be helpful too.
