2005--any way to get around cyl deactivation?

Yeah this should be a stock Tahoe 5.3 with wiring. Is that all aluminum one the vho I hear of?..I am going to try and squeeze the pcm and alt and power steering out of the guy at no extra charge I'm still on the fence as to whether to swap out for cable TB or not. Then it should be pretty run-of-the mill to get the pcm programmed :claps:

The VHO was the 6.0. When they released the L33 5.3 HO, they changed the VHO package to the Vortec Max. I'm pretty sure the aluminum 5.3 was only offered in Ext. cab 4 wheel drive trucks.

The DOD oil passageways should be easily disabled with an LS2 valley cover replacing the stock unit. You also could drill and tap the passages to block them off. You will need to replace the two stage lifters with single stage lifters. You may also need to replace the lifter trays. You will have to verify that when you get to that point.
