Re: Junkyard Jimmy Super Low Buck Build Thread

No real progress but I did buy some drivetrain parts. I had been using the standard sbc with a TH350 tranny and NP205 transfer case. The engine is now in my C10, the tranny wasn't going to last behind more power with bigger axles and tires and I want overdrive. I picked up an LM7 5.3 out of a silverado, just like what I swapped into the C30 crewcab. And today I got a 4L80e and NP208 from a 91 suburban. There's also a possibility I might turbo charge it, I have an exhaust set up for a turbo in a parts car. At the very least it will get a cam and valve spring upgrade. I will be looking at doing a slip yoke eliminator too.

I haven't been working on the Jimmy this winter. Probably won't until next winter. Really going to focus on the crewcab next. And I need to finish repairing the Dana 60 for the plow truck. Just got a few more parts for that and the 4.10 gears for the rear axle so they match. It's got 4.56 gears now and no overdrive.

Anywho, just a little update. Go build something!
