Seconding cam (you probably also need to move to a torque converter with a higher stall speed with this) and headers. Also, the 4.2 getting that low of gas mileage is hilarious to me. The 5.3 in my avalanche managed to get ~26mpg over a 3k mile roadtrip that included me driving it like a gaping dickhole through the ozarks and doing 90 most of the time I was on a freeway. Still wish I had a 6.0 though.

Except the that engine should have a metal heat shield surrounding the bottom of the wire to protect it from the exhaust manifold. Gm says gently caress your fancy tool.

Is it one of those 16" steelies off the base silverado? I know thats what the avalanche and suburbans had as a spare, but not sure about the escalades.

Yu-Gi-Ho! posted:What year did the 5.3s start getting DoD? The knock sensors sit under the intake manifold in recessed holes in the valley pan. They will rust out and die. Replace both at the same time along with the section of harness leading to them, dorman makes a decent replacement. Also put a ridge of rtv around the holes to extend the life of the new ones. The evap purge valve and solenoid also love to poo poo the bed. Other than that and possible piston slap issues due to it being an '01, its just regular maintenance poo poo.

Its not bad, just irritating and almost assuredly going to happen.

That obx setup should have it coming out just like the borla so long as it matches the pic youbposted. Granted, Its now been almost 9 months since I've looked at the exhaust of a gm suv/truck that closely.
