Craig Boone designed his motor to power this G-machine rapidly through the turns and quickly down the dragstrip. The 421-inch small-block is built from a Motown all-aluminum block that is topped off with AFR heads modified by Slover's Porting Service in Sun Valley, California. Ollie's Machine Shop in Van Nuys, California, completed the engine assembly. Fuel delivery is electronic with an ACCEL DFI unit. With 445 rear-wheel horsepower, Craig spends Saturday afternoons looking for unsuspecting Viper and Z06 owners. The F-body keeps contact with the ground using suspension items from DSE, Global West, Hotchkis, and Guldstrand.
