Yes, my understanding is the 98/99 models years dropped the CR to 20.2:1. There were plans to drop it to 19:5:1 but the intro of the Duramax killed that idea.

Putting the ideas together on my engine build. This past week I found a short block sitting in a machine shop in the Boise area. Crack free!!. The deck has been milled/lightly touched...supposedly. I need to check that out and make sure pistons are sticking out of the holes. Missy has been a...

I use Eastwood's Epoxy Primer and their Ceramic Black Chassis Black. Two coats of primer and three coats of black.

No. The 1 Ton frame is stronger than the 1/2t or 3/4t frames. Besides this frame survived United Pacific abuse on the railroad tracks.:) Now it is time to get the suspension done. I am also looking for a good engine machine shop in the Boise area. I emailed Patric Crow and he gave me a lead on...

Pictures The frame was painted this past weekend. I thought I would share a few pictures.

I should have mentioned that I already have the NP241. About 6 years ago I swapped in a SM465 and NP205. The 700R4 was a piece of junk. I took the NP241 out and have carted it around. I still may use my NP205. Called a couple of the engine machine shops in Boise. That was a disappointment. One...

I will be running a 6" lift with 37" tires and 4.11 gears. this is not going to be a hard core boulder cruncher. Mostly a daily driver, camp, hunt, haul wood...that type of thing.

My understanding is the Optimizer engine was used in all military hummers after about 2000. I am assuming that I can put a turbo on a naturally aspirated engine. It seems that when GEP got involved with this motor they brought in International to help with the metallurgy. My understanding with...

Any one know of a good engine builder in the Boise area?

So then what do I go and do. I buy Diesel Power Mag and they have a build going on where they are swapping a Cummins into and OBS Suburban. Hmmmm!:hihi:

I appreciate all the comments so far. Yes I did consider the Cummins and even though it is a popular swap, it has a number of issues to consider. Least of which is cutting part of the front cross member. Again I am not looking particularly at trying to make a whole lot of hp. Reliability is...

I don't have an engine yet. I purchased the truck without an engine, transmission and transfer case. Perfect for what I was planning on. I do plan on using the NV 4500 and a NP 241. The first obvious question is whether or not to rebuild or to maybe purchase a GEP. If I rebuild Bill said to find...

I need some help and Bill Heath gave this site a thumbs up when I talked with him this past week. I have a 1985 K30 Crew Cab. I have modified the frame to accommodate a short bed. It is going to be a complete frame-off restoration. I would like to keep this all GM including the engine. I am not...
