When Pro Stock Motocycle racer Eddie Krawiec decided to build himself a street machine, the Vance & Hines Harley-Davidson team rider made sure the '66 Nova was going to be a cutting-edge street machine. All the best suspension goodies from Chris Alston's Chassisworks ensured "Project Getaway" would ride and handle like a champ. But what about the engine? When you earn your living accelerating to 192 mph on two wheels in under seven seconds, your hot rod has to be able to get the adrenal glands pumping in a major way.

With that in mind, Krawiec put in a call to Turn Key Engine Supply in Oceanside, California, for one of its blower-ready 408 LS2-based engines and another to Kenne Bell Superchargers in Rancho Cucamonga, California, for a twin-screw supercharger. Turn Key whipped up an 8.5:1 compression stroker engine with Dart Pro1 cylinder heads. Atop this went a 2.8-liter Kenne Bell blower.

When all was said and done, the resulting engine was a masterpiece. It delivered 778 horsepower at 6,600 rpm and 710 pounds of torque way down at 3,700 rpm-on the swill known as 91 octane California pump gas.

For the sake of science, we bolted on the 2.5-inch pulley and ran the 408 on 114-octane Rocket Brand race gas. The result was 803 horsepower at 5,650 rpm and 813 ft-lbs at 3,700 rpm. We had to stop the pull at 5,650 because the injectors were maxed out! This lightweight Nova is going to put the hurt on those giant 20-inch Nitto tires Krawiec ordered.

On to the build!
