Recently picked these two K30's up. Well and a few others..
87 454 TBI TH400 NP205 3.73's. Kind of rough. But It'll get better... Slowly. Got it with no bed. Through some Craigslist searching I was able to find some body parts to make it solid again.
Found this clean bed about 40 miles south. Came off a retired Air Force truck. No tailgate but those are easy enough to find.
I thought I had a pretty nice thing going on until I found this!
86 K30 350 SM465 NP205 4.10's Originally had a 454, but it had let go at some point and this replaced it. Unfortunately this motor has issues as well, but the truck is CLEAN!
87 K20 came with no motor. Has SM465. I have a TBI motor that should be going in within a couple weeks.
I have a 90 suburban and a 95 2dr tahoe that I put snow plows on last year.
grenaded the already worn out rear end in the suburban.... so it got the 1 ton treatment, rear locker and 4.56 gears.
