Description
Industrial Injection's Race-spec 5.9L 12V Cummins long block for 1994-1998 Dodge Ram 2500/3500. A fully assembled, sim-tested race engine built on a balanced and blue-printed rotating assembly with Carrillo billet rods, Stage 2 cam, and a Stage 1 race-ported cylinder head — ready for serious competition use right out of the crate.
The short block is built on a machined and blue-printed 5.9L block, balanced Cummins crank, Carrillo billet rods with HD bolts, and fly-cut/coated/chamfered pistons with .010 off the top and .100 valve reliefs for high-RPM clearance. The 14mm Gorilla Girdle and ARP main studs lock the bottom end together. Stage 2 race performance cam runs on cam bearings installed in all journals to prevent block wear, and the rotating assembly rides on coated H-series main and rod bearings with billet freeze plugs and the Premium Killer Dowel Pin kit installed.
The cylinder head is a Stage 1 race-ported unit with hand-blended CNC porting on valve bowls and intake/exhaust ports, new diamond-honed valve guides and stainless steel valves, ARP 625 head studs, 150 lb performance valve springs, a radius-cut fire ring head gasket on a milled/fire-ringed deck, and drilled-and-tapped coolant freeze plugs. The intake shelf is machined off to accept a ZZ Fab side runner. Comes with rocker assembly and stock pushrods (upgraded pushrods available).
