what is your experience with max streetable (daily driven)compression for a stroker motor, long duration cam 306-deg, good heads etc... running premium unleaded.

I am hoping to go to 9:1.....????

cheers

I think Cal-com and most people engine builders agree 8.5 is probably the best for street due to the requirements of day to day traffic. Try getting caught in a traffic jam with a high comp motor and see what happens.$$$$$$ my2c
