Well I got tired of the nasty egr manifold on my engine, so I got an intake from a military 6.2, and a set of the exhaust manifolds from a hummer, they look like headers. I got the intake bolted on only to find it a full two inches shorter than the stock manifold
..But Lumpdog came to the rescue with a spacer made out of pvc sewer pipe..(Thanks, I owe ya one for that!) Which allowed me to place my stock air cleaner back on. I also got a new set of injectors installed. As near as I can tell, the originals had at least 155k on them...maybe more. I'm happy to report the truck is starting to run real nice. The exhaust may have to wait till spring, but I'm happy with it.
