489 Chevy Long Block
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 550 horsepower version is designed for street performance. It combines a lopey idle with decent vacuum and excellent low end power for the ultimate Muscle Car upgrade. Starting price includes base engine from valve covers to oil pan, dyno tested, and backed by 3 year warranty.
