When building a stroker, one key player is the crank. When we called up Lunati we wanted to order one of their Sledgehammer engine kits (PN EA55-540-S, $2,670). They feature a nitride heat-treated crank forged from 4340 non-twist steel. The bad news for us was that the crank in the kit (PN BP425IN, $740) was on back order. Since we had a deadline, Lunati substituted their Pro Series crank (PN BP421IN, $1,680). The Pro Series crank is the best they make, since it can handle over 1,500 hp. Granted it’s overkill for this build, but man it sure is a sexy American-made crank. Hey, at least we know we’re set if we decide to toss in a big shot of nitrous. If you’re looking to duplicate this build, pick up the wallet-friendly Sledgehammer kit that includes the crank, rods, pistons, bearings, and rings.
