New to the GTO Performance Airboats lineup, the small block 427 engine has the weight of a small block with the performance of a big block. We start with a new Dart SHP Block with a 4.125bore, Splayed 4-bolt main cast iron block, forged internal rotating assembly, 10.1:1 compression ratio, and aggressive hydraulic roller cam. The engine's top half includes a pair of CNC ported AFR heads, the intake is a matching high-flow Victor Jr. aluminum piece. With 590 ft/lbs torque and a conservative 590 HP rating, this is one of the best engine choices for an excellent performing ride boat.
