Proper DoD delete oil pump

[Rokjhn]

For what it’s worth, I just finished installing a rebuilt 6.2l engine in my 2009 Denali. Engine came out of a 2013 Yukon with AFM\DOD and VVT. Deleted AFM\DOD and kept VVT. Bored cylinders, new pistons, rings, bearings, TSP Stage 1 Cam, etc…. And I installed a Melling 10295 HV pump. Engine runs and sounds great. Cold start pressure goes up to 40-50 PSI and once warmed up it’ll idle around 10 and hit 40on a hard pull. Seems to follow the 10 PSI per 1k RPM rule somebody told me about.

That's one of Smokey Yunick's guidelines. Dunno if he was the originator, though.

FWIW, the aluminum engines should really get the high volume pump. I have the Melling HV in mine as well, and see 50 on cold startup, 15-20 at idle and 45 when towing hot.
