Okay. I am going to build an engine next month. Was going to go with high compression 11.5-12:1 compression. But after realizing with the help of many of you that I would be shooting myself in the foot by screwing myself out of a blower in the future, I decided to back down the compression. What would be strong without a blower, and stronger with? 9.5:1? 1976 Stringray. I am going to do a chevy 350. I want to run low to mid 13's without the blower. I do cruise around with my car. I have a 3.08 gear, will upgrade, and a 700r4 trans... 2500 stall speed. All help is appreciated....
