      My friend had a 79 Camaro. It had a small block 350 all built up to the nuts running 12.5 CR. I cant remember exactly what he had done to it. But he put lots of money into it. He ran on pump gas.

      I am sure our cars would be a lot less though. But I really dont know for sure.

              Nah, I'm not going to move it.
              I figured it was for a nitrous engine.
              Well, I've been looking into my super engine.
              Compression ratio (for a dual stage 200 shot max and 150 shot min) will most lilkely be 9 to 1 or maybe slightly lower

                  too much cr can cause detonation, even w/ nitrous, because pressurized gas gets hotter easier.

                    Well, I plan on uping the nitrous shot much higher with a built motor.
                    With all that nitrous you do need to lower the compression ratio.
                    I am talking about shots in the 150+ level.
                    I've been learning more and more as I look into a super engine
