As power numbers and RPMs go up, you should plan to increase your budget in order to step up the quality of components required to add durability to the rotating assembly and valve train. Here is a little chart to clarify the Alcohol vs. Steve Schmidt Racing Engines - Your trusted source for High Performance Race Engines and Race Engine Parts. 7-liter, small-block V-8 displaced 350 cubic-inches and had an overhead valve configuration with cast-iron blocks. But since Hawaii has such great (dense) air and the car will be running high octane fuel, the final compression ratio turned out to be a calculated 9. Compression Ratio. 6:1 due to the smaller chambers. The half point of additional compression works better with the retrofit roller and the higher flowing heads. Used a wide ratio Saginaw 4 speed, to a 57 Chev rear, with a 3. also with that tight of clearance compression can be high with the wrong head. I was curious about the octane I should be running in my car. Mechanically To put it as simply as possible. Compression ratio. compression ratio and six psi of boost is an initial setting of 18 degrees BTDC and a total of 30 degrees of advance achieved at 3,000 rpm. Why not leave it at 10 to 1 and just run less boost ? B&M used to have a chart that showed boost vs compression ratio.
