Dressed 88869604 CT400 IMCA-Sealed 604 Chevy Crate Engine, Dynoed

If you're competing in IMCA racing, you need an engine that's been verified for performance and sealed for compliance—not a gamble on unknown numbers. This dressed 604 Chevy crate engine arrives dyno-tested and broken-in with factory-set timing and lifter preload, meaning you bolt it in and race without guesswork. The included distributor, spark plug wires, and fuel pump block-off plate eliminate sourcing hassles and get you track-ready faster.

Every engine includes a dyno sheet with verified horsepower and torque figures. The piston rings are broken-in using a proprietary program to maximize ring seal and horsepower retention from day one. You're buying certainty—not potential.
