We've got a genuine Cummins ISB 6.7L / QSB6.7 cylinder block, PN 4990447, available as a core. This is the bare iron casting — no crank, pistons, liners, or head — for anyone rebuilding or machining a 6.7 Cummins block.
Fits the common 6.7 Cummins applications: Dodge/Ram 2500/3500 (2007.5 and up), Ford F-650/F-750, Freightliner and International medium-duty trucks, plus Cummins QSB6.7 industrial and off-highway equipment. This number also cross-references to 4946585, 4946586, 4955412, 4991099, 4932525, 5302096, and 5405093, so it's worth checking against your build tag even if your number doesn't match exactly.
