NOPE, No 2.8's Forerunner of the S-10'S & S-15'S
Streets I just bought '86 GMC Caballero with 4,3L V6 &TH200-4R.
I'm interested to know what are these 8cyl; 3.3L,3.8L,4.4L engines???
Could anybody tell me why General Motors makes both Chevrolet and GMC trucks (GMC=General Motors Corporation????)
Does they have a different dealer network or something??
