Mark's 94 LT1 Vette has a TPiS built 383cid engine that produces 505hp and 450 ft/lbs at the flywheel. Compstar rods and crank are topped off with SRP pistons to complete the rotating assembly. Dart Pro1 200cc heads with 58cc chambers sets the compression ratio at 10.8 to 1. The TPiS 1-3/4" primary long tube headers and 3" exhaust makes sure the 383 breathes properly and 3:73 gears were installed in the diff. for quick acceleration. A big brake kit makes sure he can stop and some black grand sport ZR1 wheels give it a special look.
