Cost of a good used DDEC 4 12.7?

Should have steel pistons, and 1650 torque

 

It's cheap. Can you run it on a stand? Would that be even worth doing? Just throw it in????

 

Why not just rebuild the old one?

 

When the 14L came out, it started at 500hp. 12.7 went back to being 470hp Max. It was sometime around 02-03 maybe that’s why the new engine is a 470. Just an idea. Either way, 470 always had better fuel economy. Must be the injectors. Don’t know. Not sure about the newer ones. Pistons are 16:1 on 99 BK and newer. Not sure when, but they had 17:1 pistons later. Maybe Marine only. Don’t know for sure. Just some things to consider. If blocked drilled, rebuild kits come with new nozzles. You can rebuild with a BK kit. Pk pistons cause the white smoke, till warm. Probably from the LO NOX reprogramming that supposed to be done at overhaul. Might want to find a drilled block, pre 2000, to build the original. They also have drilled rods available. Be nice to build it your way, instead of most shops, that will only replace with original. Any of them are fine, as long as your not going racing. Higher HP tunes, need the best stuff. So I’ve heard. Haven’t had mine tuned yet. Kind of Leary about it all.

 

Years back I inframed two engines that customer bought of which had been sitting several years. They were out of wrecks from a major fleet with low mileage on them and looked nice. After they installed them immediately got coolant in the pan. Dropped the pan and coolant was leaking past o-rings. Apparently o-rings dried or shrunk as they continued to leak until overhauled. I have been afraid of an engine that has sat up dry since then. Just something to be aware of.
