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 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.

Dyno testing not included in long block price. Here at Prestige Motorsports, our “Dyno Promise” means that we dyno test every engine we build to verify the quality of our work, the integrity of each component, and the reliability of every engine we construct. Then, we deliver the dyno results for your project directly to you, the customer. Hours for dyno testing will be calculated with the purchase of the fuel and ignition group per engine order.
Engines will produce +/- 2% of advertised power at the flywheel. Advertised power levels are achieved using an electric water pump and specific induction and exhaust systems. Power will vary after pulley systems are installed or if changes are made to the induction or exhaust system (e.g. camshaft, cylinder head, compression, intake manifold, exhaust headers, air filters, etc.). Chassis dyno results measure power at the wheels and only calculate flywheel horsepower. Wheel horsepower is affected by a variety of vehicle-specific criteria including driveline design, body and chassis flex, air intake location, etc. Therefore, calculating flywheel horsepower from wheel horsepower is not an accurate representation of actual flywheel horsepower.
