1979 Chevrolet Malibu Engine Bay View
You’re looking at 477 ci of big-block mayhem with a 4.500 bore, a 3.750-inch–stroke Callies crank, GRP aluminum rods, and a set of Wiseco custom pistons that bump the compression to the tune of 14.0:1. It gulps air through a Holley 4150 series carb on top of an Edelbrock Super Victor intake with a set of heavily ported and milled cast-iron GM Performance Parts aluminum heads (Factory Street only allows stock factory head castings, or heads that come installed on a crate engine, like the 502/502). The fumes are expelled through 2-1/8-to-2-1/4-inch–step Hooker Super Competition headers with 4-1/2-inch collectors, 4-inch piping, and Dynomax Bullet mufflers. The results are an astounding 660 hp and 700 lb-ft of torque to the rear tires, along with solid, 9-second jaunts.
