4bt swap in to a 1999 GMC Sierra 2500

[nicklatech]

I picked up this truck at the local u pull it salvage for a few dollars. It actually ran great even with 220k miles on it and the title says it was owned by an oil field company which is why the trucks interior is covered in tar/oil/sand/dirt as is the entire under carriage of the truck. But, it was cheap.

Am tuning in. 4bt is in my long term plans for my c1500. Pretty clean considering it was an oilfield truck lol

 

[mater86]

this is going to be a pretty cool setup once done

 

[92silvy]

This is certainly going to be interesting. I only gotta wonder why not a 6bt? Still cool nonetheless

 

[someotherguy]

Turn that sucker into a dually and run those 8 lug 19.5's off the bread truck!

Or at least sell 'em; people like those wheels. I sold my set for $450 several years ago, just the bare wheels, no tires.
