Compression ratio

The weight of the car you've got that engine in makes a differnce too. My old T bucket roadster had a PowerPack 283 punched to 292 with a solid lifter cam and 12.5:1 compression. I always used straight regular cheap gas and never had any problems with heating or detonation or dieseling, but that same engine put in a 57 Chevy wouldn't perform well without high-test.
