John Schaffer's super impressive 383ci LT1 really cranks out. Complete with a TPiS MiniRam, 58mm throttle body, solid roller cam (242/242 @ .050" - .612 lift with 1.6 rockers, and AFR 210 cylinder heads. This engine pulls hard all the way to 7000rpm, making it a potent street and track day engine. 553hp @ 6500rpm and 485 lbs/ft @ 5800rpm making over 400 lbs/ft from 2500 to 7000.
