One of the coolest street Pontiacs to be built at Spotts Performance is Pete Horton's blown 428SD. The 871 BDS blower twists pump gas from the demon carbs to a race prepped 428 4 bolt block with a 1963 421 SD forged crank. A special grind Comp cams hydraulic roller with Scorpion rockers activate the valves in the Edelbrock heads. The cnc ported E heads with 91 CC chambers and the dished Ross pistons (with Crower rods) combine for a compression ration of 7.6 to 1. Pete plans to drop this combo in his 68 GTO.
