In the continuous pursuit of horsepower, bigger is always better, and that’s where S&S comes in with their biggest big bore kit yet! Take your stock cases or their recently released MK-Series crankcase and match them to these massive 4.320” bore cylinders and pistons. When paired with the 4⅝” Stroker flywheel, this combination results in a heart-pounding 136” monster of an M8 engine that still perfectly fits in the stock chassis. Available with highlighted fins, non-highlighted fins, and Black Granite options, there is sure to be a finish to fit your build.
