Run up front with the 400-horsepower CT400 crate engine (often referred to as the "604 crate") featuring Fast Burn heads from GM Performance Parts. Now, Speedway Motors Racing Engines is offering this 604 crate engine as a dyno-verified package that is ready to race! These IMCA-sealed 604 crate racing engines are based on the popular Fast Burn 385 street crate engine, but include a racing-only 8-quart circle track oil pan with dual kick-out design, along with a valve cover breather kit and special "kool nut" rocker arm design. The assembly also includes an open-plenum high-rise intake manifold and 1.5:1-ratio aluminum roller rockers. The 604 crate engine includes a bulletproof bottom end, anchored by a forged steel crankshaft and hypereutectic pistons.
