Ford 306/331/347/363 Race 8 second DART Sportsman Short Block
Our 306/331/347 Race 8 Second Dart Short Block is designed for 800hp-1200hp vehicles looking for a strong foundation for high horsepower. This shortblock is balanced to 28oz and ready for your big horsepower street or race car. The extra strength of this setup relies upon a 4340 forged steel crankshaft and set of 4340 forged steel H beam rods along with the Dart 4 bolt main 302 block. This is the premium 4 bolt iron block available for 302 based motors and can handle upwards of 1500hp. For lighter rotating assembly parts we also have high strength 4340 I beam rods, and Ultra light 4340 I beam rods for quick and high revving naturally aspirated engines. Don't hesitate to ask us about custom internal parts for your exact needs, wants, and application!
