1971 GMC Sierra Grande K25
A few weeks ago I found the truck I wanted around 100 miles from home. I bought a 1971 GMC Sierra Grande K25 with the intentions of putting a ls motor/over drive trans in it. I bought the truck running and driving and drove it home without issue. I wanted a 4x4 3/4 ton with ac and I found one that was fairly clean. Over all I want the truck to end up being a clean daily driver. The truck came with dana 44/dana 60 axles, 350/sm465/205 drive train, wood bed, ect.

Plan:
  • 6.0/4l80e/205 t case
  • Frame sandblast/restoration
  • Cab sandblast/restoration
  • Rocker replacement
  • Interior restoration
  • 2-4in ez ride tuff country lift
  • Get the ac working
Hopefully this will be done by spring

Just curious, whats a fairly clean, running and driving k25 worth?

Nice start. I'll be watching this cause if my 355 ever blows in my 4x4 I'd love to put an LS in it's place.

Re: 1971 GMC Sierra Grande K25
I've been busy the past week so haven't messed with it. I did however receive my t case and t case adapter back from the machine shop this week! I'll be mocking up the motor/Trans/t case soon then the frame will be getting blasted.
