JRPW Signature Series Pro Big Block

The King of the Hill, the Leader of the pack! Definitely not for the timid. This Monster is 460cc of pure Evil. Billet parts fill the inside and adorn the outside. Billet ARC crankshaft, Billet ARC rod, forged piston, Billet Cam, Billet Flywheel and Billet Crankcase cover are a start.

The block is expertly welded for reinforcement, and topped with our Attack Series cylinder head with 40/33 mm valves. Roller Rocker arms and HD pushrods complete the top. Completed with a 33mm Pumper Mikuni, this one is ready to roll.

Powdercoated Housing in color of your choice is standard.
