Default With a stroker motor with aluminum heads what is the compression ratio limit for pump
Is 10.5 to 1 a safe doable compression ratio for the street on 91 octane with a 461ci with aluminum heads? I used to think so, but I have guys telling me that it is pushing it. Where are you guys at with your street cars that are pushing 500+hp? the cam I'm using is 521/540 lift .050 is 236/242 on a 110. Please share

Thanks
