I had a 71 Camaro with a SB 400, M22 4 speed, and a 3.73 geared 12 bolt. It had the second design "offroad special" GM solid lifter cam. It's not real tame. I had 2" primary tube hookers on it with 3" exhaust and 2 chamber flowmasters to the rear end with turn downs. I was working at the local Toyota dealer then. They would have to reset car alarms everyday after I pulled in for work and left. That thing was loud. But it sounded badass.
