Hey folks, what happens when you take 97 pistons, 4 cranks, and 2 rods and put them all together? You get 227 different Rotating Assemblies, Piston and Rod Assemblies, and Crank and Rod Assemblies. We added a couple 7.0L parts as well that will be coming into stock soon. We've got Clevite HX bearings in those kits and the steel rings too. All kits are $1999.99 regardless of the combination to keep things simple. Here's a video that covers some of the the high level design features we've built in.
