Here we got a 2005 5.9 Cummins, common rail block that is fully remanufactured and ready to assemble. This block has been cleaned, fully inspected, linebore checked, it was re machined in a state of the art CNC machine to be resurfaced, and bored oversized all in the same set up, and then over to a CNC diamond hone for the finish work, rewashed and painted, and had the cam bearing replaced. This block is ready to assemble, priced at $1750, also can get you an engine kit, crank, rods or new cylinder head if interested.

So it's been a while since posting anything on here, we had a busy summer here with a lot of different projects. Biggest of which was getting a new RMC V50 CNC mill, with a fourth axis rotary. Huge shout-out to the awesome guys at RMC for hooking us up with such a nice machine, this thing is even better than imagined!!! We purchased this machine with the customers in mind, to help decrease back log while adding superb quality into the machining process. Plus making it so much easier/quicker to do stroker clearancing, four bolt main conversions, true blueprinting of the block, and also lifter bores/bushings!!
