Does anyone know how to figure out compression ratio without ripping all kinds off stuff apart... like a easy way? When I bought my motor I bought it from my buddys dad... his son had built it but passed away but he didnt know all the specs on it. I was told i have to run race gas but I have no clue how high of octane or anything... It would be nice if i could figure out my compression but i dont know the headgasket thickness or what pistons are in it? or how much was shaved off the heads... Im running CAM2 110 right now to be on the safe side but if i could run lower i will, this stuff is killing me @ $7.90 a gallon
