Been working hard this week. Tore down the engine in this 2019 Silverado LD 5.3 L83. It had a cylinder 6 misfire due to a AFM lifter failure. Customer requested a full delete of the AFM system. Replacing the camshaft with a non AFM BTR stock replacement cam, Delphi LS7 lifters with correct length pushrods. Cylinder heads were also reconditioned with a nice valve job, new seals and a resurface.
