Tool Stroker Combinations

The new Dart Special High Performance Chevy small block engines are manufactured from high-nickel iron for superior strength and feature siamese cylinders with 4.000 or 4.125 in. bore sizes. The cylinder walls are a minimum of .230 in. thick at a 4.165 in. bore. The Dart Special High Performance blocks are machined using precision, digital CNC equipment and are virtually ready to assemble right out of the box after a final cylinder hone. The decks are even and parallel within .002 in., and the lifter bores, cam, and main tunnels are finished. The Dart Special High Performance blocks are designed for compatibility with stock components, so no costly special parts are required for assembly.
