My 318 has less compression, 9.4-1 but it does have more cam, and edelbrock heads, but not that racier, 89 octane fuel, street car, drove to and raced at the track, i am not sure how much power it takes to run 11.70s in a 3000 pound car.
I am going to be building another one next year with more compression, so it will interesting to see how it runs.
