so i just bought an 86 chevy suburban 6.2l turbo diesel. yes its turbo. ive heard of people doing a cummins swap so this spring i will do so wheres a good place to buy motors

 

Search Craigslist for "diesel farm truck" "work truck" "welding truck" "deisel" "cummings" "dodge diesel"...

Getting a complete donor truck will generally greatly simplify things for a swap. And it's not terribly hard to find a ragged out Dodge with life still left in the engine.

Just my $0.02
