Just dyno'd a recent build we did. It's a 482 street motor, idles at 800 rpm, pump gas compression, TA SE Stage2 heads, mildly ported, 330 cfm on the intake, SP1 intake,took the rpm to only 6000 since its primary duty was to street drive it and thats where we designed it to operate at a max. Made 605 lb-ft of torque at 4800 rpm, curve was very flat, and 627 hp at 6000 rpm. gary
