Originally built and freshened up by Joe’s Performance Racing Engines in Ft Myers, FL. “0” miles, no time on it since the freshened up. It's a 383 CID stroker crank, road racing, blueprinted, LS, long block assembly. This motor is really fast and ran a lap time of 2:18.4 in my 3000# Corvette on the Sebring International long course just before this recent rebuild. The last engine dyno run was 602 HP @ 6700 RPM w/ 532 # ft torque @ 3900 RPM at the flywheel. It comes with the original Superflow engine dyno sheet.

This LS long block motor includes the following parts:

Stock LS-6 heads with port work & bowel blending. 1.600” exhaust & 2.020 intakes

Crower roller cam with .570” intake lift & .559” exhaust lift and 232/241 degrees of duration @ 50

Forged Ross pistons with 11.5 to 1 compression ratio
Everyone knows Tony Mamo's 383, right? AFR 225 heads, 242/248 solid roller .646/.653 114 LSA...
