I essentially have the bottom end of a Winston cup car with 7:1 compression. Red line is 7600 rpm but I have a pill in my msd 6al for 7000 rpm. Saved me many times.. Forged everything. Iron heads from dart. It's an old motor. I go through it every 3 years or so. Dual 3" exhaust with "H" pipe and single chamber flow masters that dump before the rear end. It thumps pretty well at idle. When ya give it some throttle it whines like an airplane.
