All the parts for this complete engine package were supplied by Butler Performance. We’ve taken it from a truckload of parts to a completely finished, running engine. It has all the goodies including splayed 4 bolt main block with billet caps, forged crank and pistons, H beam rods, all ARP hardware, hydraulic roller valvetrain, Edelbrock aluminum heads and intake, MSD ignition, and a lot more. Smokey is gonna need a bigger engine if he’s gonna keep up with this Bandit! Enjoy!!
