I watched Bob Mazzolini race his 318 years ago. Cast iron heads, low compression pistons, QJet carb. Made more than 500 hp, ran low 10's in a Sebring. Very high dollar engine with a high dollar transmission and a high dollar car. It would yank the front end and go. He used a cast crank since it was lighter. Not sure on the RPM, well north of 7K.
I think the compression ratio in Bob's engine was 8.9 and he used some 360 cast iron heads but I don't recall the part number. Car was around 3200 lb and it ran low 10's. When I saw Bob's car run it really woke me up to the fact that there is a big difference between what most people think and what is possible with some dedicated effort.
