1996 GMC Sierra

Engine Mechanical problem
1996 GMC Sierra V8 Two Wheel Drive Automatic 99786 miles

if I swap the 305 fuel inj engine on my 1996 gmc sierra with a used one, is there a year range as to which engine I can use and could I swap it with a 350 fuel inj without having to do any modifications or reprograming of the computer. If so could you please provide me with the information needed to dicide which way to go.

Yes I believe you can. Your best bet is to contact salvage yard, they have computer program to cross reference years and sizes, I dont.
