In 1997 Hermann Stolzenberg from Horsepower by Hermann built Mark's current engine. Using a vintage '68 302 block, Hermann made the necessary clearances to the block and stuffed in a Scat 4340 stroker crank, Eagle rods, and JE flat-top pistons with Total Seal rings. He also ported the Edelbrock Performer heads and a Victor Jr. intake, and added a Lunati 51018 camshaft to the mix. Hermann blessed the intake with a Barry Grant Mighty Demon 650-cfm carburetor. Mark ran this combination for a couple years before squeezing in an NOS Big Shot plate nitrous system, which is now pilled to deliver 225 extra horsepower on demand. A testament to Hermann's talent, the combo makes 672 hp and 650 lb-ft of torque, and lays down mid-9s at 140 mph.
