Main, rod and cam bearings, a standard-bore piston ring set matched to your engine's ring grooves, head and lower gasket sets, crank seals, plus optional cam, lifters, pushrods, valve springs, timing set, oil pump and a rocker trunnion upgrade.

No. Order the parts kit and every part drop-ships from our suppliers to you, with a machine-shop spec sheet you can hand to your local shop. Or bring the engine to our Glendale, AZ shop and we rebuild it.
It's on the Service Parts Identification sticker in the glove box, console lid or spare-tire cover. You can also match the 8th digit of the VIN.
