Very nice build. What type of paint are you using on the block? I would like to find some of the same thick paint that Cummins used for the original paint job.
Equip. Junkie yes that is the tab method to retain the KDP.
The pistons, bearings and bottom end are aftermarket, got them from Diesel Specialists. Don't remember which brand, I want to say it was Federal Mogul but I'm not home to check. The upper gasket set is Cummins.
