With the removal of the engine and supercharger assembly; polishing and porting of the cylinder heads; and a variety of other internal improvements, the upgrade will boost your already super Corvette to an insane 750 hp and 730 lb-ft of torque, 40 hp more than Lingenfelter's cheaper ZR1 upgrade and 112 hp more than stock.
