This kit is for a good duner or drag race combination. This kit will work with all Stock Stroke Applications, and several stroker crankshaft options. We recommend using a Carrillo Rod Crankshaft with this top end kit. Head Porting, Camshafts, Intake and Exhaust Modifications, etc. are not required, but are highly recommended to get them most out of the engine combination.
The Cylinder in this kit requires Crankcase Machine Work for installation.
