Based on the 454 Big Block Chevy, our 489 stroker offers a longer stroke which boosts torque and horsepower output to get your heavy classic out of the hole and moving quickly. This 600 horsepower version is designed for street/strip performance. The rectangular port heads make for a top-end power house that will turn heads on the street and at the track. Starting price includes base engine from valve covers to oil pan, dyno tested, and backed by 3 year warranty.
