Re: Newbie, Buying my first. 72 GMC K20
Yep you could. 87 is fuel injected in all square trucks, the blazers, suburbans and crew cab 1 tons squares all ran until 91. Gm kept the tbi in the trucks until 95. In those year trucks the only overdrive auto would have been the 700r4, except 94-95 which had a 4l60e.
