    LMAO, I wasn't sure if it was going to sound as good on video as it does in person.

    Yeah, me too. We're probably gonna have to put some water or something down to make both break free, but at least it's done. We're both stoked, it's been taking up space for some time.

    I thought about that. I may be able to run it on Advance and see if it shows what drivetrain it had. The RPO codes are specific for an individual vehicle, I don't even think it was there when we had it lol

    Only info I found on the difference was the number of gears in the planetary, the 85 has 5 and the 80 has 4. Other than that you can identify it by the RPO code, which we don't have access to since the RV is gone now. I agree, being from an RV I bet it's the 85 since it's rated to 18k lbs...

    Also, I understand some of you can't view the videos, I'm going to set up a YouTube account for my shop tonight and upload the videos there for easier viewing. Stay tuned, burnouts are coming

    Here's some final pics of the fabrication. If you're in the Tampa Bay area and need custom welding work done, this guy is the one to call.

    Sorry for the delay, been silently working in the background on this project. Some of the final wiring is done for the harness, just need to get the transmission connector rewired for the 4L60 to 4L80 conversion but shouldn't be long, I hired a guy that is good with electrical so hopefully...

    Heres a video revving it that Chiro asked for. Does no justice, it's so much better in person! And yes, the videos are public, anyone can see them: https://m.facebook.com/story.php?story_fbid=1080890758780678&id=282774301925665&sfnsn=mo

    The day is here, its completed enough to run it! Got fuel lines hooked up, battery, alternator, it's all good under the hood, just a few minor things like MAF, coil mounting, etc. Heres some food for your ear hole! Enjoy...

    I can't resist an update, here's some pics. Wiring is about 95% done, swapped over the original Tahoe steering pump, installed the water pump. Only a few things left while we wait for the shaft to get retubed. I can almost guarantee next week it will be on the road as long as it starts up and...

    It's entirely possible, as long as we get the drive shaft shortened and a few other things buttoned up. Definitely won't be long.

    This is it guys, the home stretch. Nathan spent the day helping me bang out a bunch of work today and we are maybe 80% of the way done! Got the harness mostly connected, just need to lengthen some of the wires. Exhaust manifolds on, distributor is in, and cooler lines are almost there. Need a...
