  • only 422 ft/lb torque out of a 548 BBC?? C'MON - at 3500 RPM maybe?? Methinks the shop boys or the owner are severely downplaying those dyno numbers for stealth's sake. That BBC sounds VERY healthy. Probably more like 650+ ft/lbs and 700+ hp. The ignorance of some of the comments is hysterical! My "little" 473 iron headed Pontiac makes 520hp & 575+ ft/lbs torque and in NO WAY would be a match for this BBC 548. Just sayin!
