The 2.8 and 3.1 GM motors used in late 80's/early 90's Troopers and
Rodeos are 60 deg V6's. Likely the 90 deg pushrod motor referred to
was a GM 4.3 V6 found in Isuzu Hombre Pickup, which of course is just a
rebadged and (slightly) restyled Chevy S-10.
BTW, the great little GM 60 deg powerplant has a Big Brother which is
pretty much a drop-in replacement for a 2.8/3.1; it's a 3.4 found in
Camaro/Firebirds '93-'95, and sold from GM as a new crate motor, HT
Find out lots of info about this swap at the greatest Isuzu forum
around, at the 4X4 Wire. Just do a keyword on "3.4 swap" and you'll be
amazed at the results.
