Is there anyone on this board with a Gen 3 motor in their 88-98 truck? I am in the process of swapping a 2000 5.3 into my 91 K1500, and I'm looking for a little insight.

 

Not that I know of! But what seems to be the question at hand? We might be able to throw something out! Generally it should be close to the same install! You will need a new harness though if you plan on going EFi with it
