whats the highest comp i can run with mixing av and 93 50-50
bbc, 572, currently at 9.7-1 comp on pump gas, aluminum heads, marine application.
Looking to make more power by raising the comp , but dont want to buy race fuel. Av gas 100-low lead, is readily available and i heard it makes a really good fuel when mixed 50-50 with 93 octane. What is highest comp ratio i could run with this mix?
