665ci Big Block Chevy Airboating Engine

This build highlights a colossal 665 cubic-inch (10.9 liters) big block stroker engine, designed by Prestige Motorsports to maximize cubic inch displacement. Featuring a Brodix tall-deck block, a stroker crankshaft, Oliver connecting rods, and AFR’s 18-degree Magnum cylinder heads and intake manifold, this pump gas powerhouse delivers extraordinary torque. It’s a testament to extreme engineering, bringing unmatched performance to the street. It is now in the hands of one of our great customers, Ken, in his airboat…built to hurt feelings in the swamps.
