Good afternoon. Here very soon I will be posting some parts for sale. They will be at a discounted price. Just making some room here in the shop. All of these parts are new, not remanufactured. There will be a long list of import cummins 6bt and 4bt parts. New crankshafts, cylinder heads, blocks, pistons and rings, bearings, rods, oil pumps, and tons of gasket kits. Got a few new turbo chargers, including a few h2e (one name brand) and one large hx80 turbo. Tons of other misc parts like gasket kits and piston sets and more will be on sale as well. Keep a look out and share to people who need to see this. Thanks.
Stay safe and have a Happy Thanksgiving from here at Altman Machine.

Quick refresh on these 317 chevy heads. Per request, surfaced the deck down to raise the compression ratio to where it should be. This LQ4 (6.0) is going to bark alot harder.
