This is the instructions I was talking about http://mattw.dyndns.org/4L80E/ If I went with the th700r4 would it still be ok for some mild towing? I have a 18' boat that weighs around 1500 lbs that I plan to tow Sent from my SAMSUNG-SGH-I337 using Tapatalk

If I did decide to go the 4l80e route I was looking at the manual control on summit racing for $232 but the reviews were mixed, or reprogramming a stock ecm, I found some instructions on that on another site, either way looks like a bit of work to get it working correctly Sent from my...

With the Cummins, I was only thinking with switching to a ram 2500 4x4 with a camper instead of this build, because it would be less work. I wouldn't bother trying to put a Cummins in this truck. If the th700r4 would hold up I would probably go that route, would I still need to shorten the...

Also It's a 14 bolt, not sure if it's Simi or full floater, some of the sites I looked at said full floater. Why go with a th700r4? I have read about issues with that transmission but the 4l80e sounds pretty bulletproof. I imagine it would get me a lot of places with that setup, and I'm...

If I do keep it, I'm definitely not painting it, still trying to figure out if I want to invest the time and money in this, and still maybe not have what I really want in the end, over buying something that doesn't require so much work. Sent from my SAMSUNG-SGH-I337 using Tapatalk

Yeah I thought about the regear, but this is such a huge beast that I think it's going to be too slow with the 3.55 and 3.73 I'm still going to be pretty limited on cruising speed if I want to get good mileage, I think it really needs overdrive. Sent from my SAMSUNG-SGH-I337 using Tapatalk

So I am at a bit of a crossroads with this van, it has been a dream of mine for a long time to build this, but now that I am looking at it seriously, the amount of time and money to do it is a lot higher than I was figuring on. At this point at a minimum for what I want out of it, I need either...

Doing some more research I think I need a gear splitter, or maybe do a trans swap to one with overdrive. Peak torque on this engine is 1850 and I would like to get my freeway rpm closer to that, it screams on the freeway right now. I might still do the gear swap but I'm not sure if I would need...

Nevermind, I answered my own question, looks like I have 4.10 gears, have to spin it twice with only one wheel in the air. I guess that explains why it seemed like pretty high revs on the freeway, I should probably either go with lower gears or get bigger tires, right? How hard is it to change...

Jacked up one rear wheel and marked it and the driveshaft for one Rev of the wheel I get ~2.1 revolutions on the driveshaft, does that mean I have ~2.10 gears? Does that seem right? Sent from my SAMSUNG-SGH-I337 using Tapatalk

Got some relatively new, used tires on the van, went with 245/75r16 they fit fine I think I could even go bigger without any issues. I decided on used tires because I didn't want to buy new ones and change my mind on the size a year from now, this way I can get it on the road while I'm building...

Cool van, why did he go with different size tires? No sticker in the door jam, doesn't have a glove box, just a little compartment on the engine cover, no stickers there. Tried to get the axle codes last night but its infested with black widows under there so I'm going to have to get some spray...

I'll check the door Jam tonight and see if it has something Sent from my SAMSUNG-SGH-I337 using Tapatalk

I have also been thinking about swivels up front but I'm in the early stages of planing the layout, want to get it on the road and take some test trips with it first. Is there a easy way to see what gearing it has in it? The 6.2l doesn't seem super powerful, with so much load, and I don't want...

I started a new thread in the van section, I can't post links, but I added more pics to that thread. Sent from my SAMSUNG-SGH-I337 using Tapatalk

Hi everyone, I posted this in the full size domestic section, but I'm thinking it would be better here. I have been reading this site for a while, wanted to start a thread to document my g30 build. It's a surplus airforce radio van, with the 6.2l diesel. 23,000 original miles. First thing I'm...

It has a frame under it, it's the 1ton drive train as well. Wouldn't think they would make something this big unibody but I don't know much about them. I'll take some more pictures and show the inside, not much inside of it, and I've started striping a couple things out of it already.

Cool ambulance, similar to what I want to do.

Well that's why I posted it here, and I had overlooked the van section before, want to post the build in the most relevant section. Either way, I'm glad to have found this forum, seems like a good place for information on building a camper like this. Paid 2,000 for it, seemed like a good deal to...

I'm trying to figure out what the best size and model AT tires to get for my '88 g30 build. I've started a build thread In the full size domestic section. I think it would be better to move the build thread to this section, but for now I'm just looking for suggestions for tire sizes and brands...
