    91 c3500 6.5/5 speed repower

    My other option would be to find a 6.0/4l80 (6l90) or even nv4500 and put a cam in it. Maybe turbo to just play with. I have other duramax trucks and semi trucks to pull with. So this would be a driver/haul kids around (since I have 3 and the wife wants another) This option is appealing as the...

    91 c3500 6.5/5 speed repower

    Yea I said 91 but I'm thinking it's 92 or 93 because it wasn't the pmd electrical pump. So its not 94 for sure. Sent from my SM-N975U using Tapatalk

    91 c3500 6.5/5 speed repower

    I think it's just a standard 3500. The HD had the bigger wheels and funky grille didn't they? Like the commercial truck? This is just like the normal pickups with 16" wheels. Sent from my SM-N975U using Tapatalk

    91 c3500 6.5/5 speed repower

    So my uncle had this truck and I worked on the 6.5 in it. He passed away and the truck got sold at auction. They pulled engine and trans out and sold it. I found the truck and bought it back. Thinking of going dmax with Allison for simplicity and finding them easier. Truck is a crew cab 1 ton 2...

    Twin turbo lml P16a1

    I have a twin turbo lml with sdp kit on it. The fuel pump was leaking fuel but he was not happy with the tuning. It was real bad laggy and derated. We fixed the pump issue. But rite now the only code it shows is p16a1 for the throttle valve that's there by the grid heater. We obviously don't...

    125k mile turbo junk?

    I got a 17 3500 that's throwing a p100b turbo code. It's all stock. We put a new actuator on it and same thing. Is this thing really going to need a turbo this early in life? Sent from my SM-N975U using Tapatalk

    Lbz swap in

    I probably have a few driver side manifolds from lml that I could put on. Yea I want to do a few things to help it run better while its out. But I dont want to tear it down and do head studs and gaskets yet. Unless I put it in and it goes to pushing water. The rig has been down over a year...

    Lbz swap in

    Hey guys I toasted my 330k mile 06 lly/lbz back last year. So finally after gathering parts and planing to build a motor I have picked up a complete lmm to just put back in and go. I would like some input/suggestions on what I need to look at doing while its out as far as parts that are easier...

    Allison 5sp: Air Flow parts recommendations

    I bought the oil supply and drain kit. Then the exhaust down pipe. So I dont have a full kit for the install. Just thought these might be good items to add when I do the install(manifolds and up pipes that is) Thanks Sent from my SM-G892A using Tapatalk

    Allison 5sp: 3500 drw lift and tire/wheel question

    I already have the ucas and my upper ball joints are close to needing replaced. Plan to do the fabtech tierods to upgrade them over the stock when I do this. The truck is a work truck. I only use it offroad when working on the farm or jobsites. No wheeling. But I'd like to go to 34-35" tire...

    Allison 5sp: 3500 drw lift and tire/wheel question

    I have a 06 3500 drw. I'm about to swap front differentials due to a gear change. I'm leveled now with 295s on my stock steel wheels. I'm looking for opinions and feedback on wether to just leave it like it is (doesnt wear the front tires funny and drives good rides good) or put a 4-6" lift on...

    lmm fuel knock misfire

    from what i just checked i don't think the crank is broke as i can put the flywheel holding tool in the trans and turn the crank back and forth. it moves just a little then stops when the tool takes up the slack on the teeth. unless someone thinks of another way to check it.

    Towing rpm range

    I've never made trips like this in my 05. But it seems to have always got great mileage empty truck on the highway. And I mean like 18-22 depending on hills and how hard I ran it. This 06 dually showed 23 on the freeway at 77 earlier in the week. But I also know pulling 25k it would run 280...

    Towing rpm range

    I just looked up my toyo at2 size. They spec them at 33.4 max inflated. So I guess I should start my calculations with a 33" tire instead of 34" Sent from my SAMSUNG-SM-G891A using Tapatalk

    Towing rpm range

    I think the 444 would put me at like 1825 running 34s and 70 mph. In 6th gear. So the 430s might make it about rite. Sent from my SAMSUNG-SM-G891A using Tapatalk
