Inspired by our Pro Stock Drag Race engines, these updated big bore kit utilizes a Ductile Cast Iron liner wrapped in cast aluminum for optimum thermal conductivity and performance. Bolt-in kits do not require machining, rebalancing or engine removal, and include just about everything you’ll need to complete the installation. The biggest cylinder bore that can be installed in a stock crankcase without machining!

- Bolts in. No machining, balancing, or splitting the crankcases
