Note: These kits are not balanced assemblies, balancing is strongly recommended for maximum performance and engine longevity.  

A quick note about the crankshaft upgrade below.... The aero-winged crankshaft will increase horsepower by reducing windage.  It has lightened holes in all rod throws and has straight shot oil holes. Another great product from Scat and Northern Auto Parts!
