Hummer H2 For those who like a little more gleam to their Hummer, the H2 offers a similar rugged look as the H1, but as a lower cost, and with more added features, making it almost a massive luxury SUV.

Engine is out and HP parts ordered, what headers

The headers and exhaust came in and I'm happy with the quality of the system, the entire system is polished SS. I spoke with them about the truck system fitting the H2 as they indicated that they didn't offer a direct fit for the H2 but that the truck system should fit with one exception, the mounting hangers may be in different locations than the trucks. They included adjustable mounting hangers with the pipes so that should resolve the hanger issue.

One thing I did stumble across is the L92 block while not equipped with AFM/DOD the block is cast for it with the oiling towers in the valley area. The valley cover has 8 seals that are recessed into a boss cast into the cover to block the oiling towers. Mine were very brittle and had not sealed for quite some time based on the impression on the bosses. I had read on the net that these seals can cause low oil pressure due to internal leakage over time. While my truck didn't have low oil pressure it was a little lower then I would have expected on an LS with these miles (around 25 psi while hot and at idle). There are a couple options to deal with the towers, one is to plug the towers and the other is to replace the seals, I haven't decided what direction I'll go for now. I'll be pulling the BRG caps and plasti-gauging them to make sure everything is in good condition and doing a good inspection of the parts while its open.

rolled the vette out of the shop and started working on the 6.2,

Pulled the pan and 4 rod caps, everything looks perfect, crank still has a highly polished finish and the bearings look new. Going to plasti-gauge them tomorrow, rotate and check the other 4, if all is good I'll clean the pan up and start on the cam swap.

All rod and main bearings looked good but the cam brgs were another story. After gauging them they were out of spec so the pistons came out for cam bearing replacement. Once I pulled the pistons I decided since it was down that far I would bring it to the machine shop and have it cleaned and all areas checked and have the cylinders honed for new rings. At this point I'm going to do a complete rebuild since I'm in the "While I'm at it" stage.

Lol - snowballing. I started doing a pretty major project on my GMC truck, redo the interior, replace stereo components, convert to electric fans. 2 years later it is still in parts.... lol. Have the bed off and just coated the frame in Chassis Saver. Have added what seems like a hundred "while I'm at it's".
