Hey GM Dad . . .
The borg-warner 4 is a nice unit.
I had an '86 half ton with one these behind a v-thingy. I bought it new around Christmas time in '86. Got it for a song as the new body style was out for '87 and the lots were full of the old style trucks. As I recall that was the last year for a carb. Had some funky air pump for emissions as well.
The only problem I had was the clutch went at 35,000. Tranny place said that the factory used some kinda aluminum bushings on the throw out -- which of course didn't last. They put in new clutch with aftermarket steel bushings. I got another 120,000 out of that with no other problems. Truck still ran great -- but 10 Cleveland winters with all that salt didn't leave much sheet metal -- had to sell.
The v-thingy with a stick was a hoot. 3.73 rear end made for smokey burn outs in 1st, but a nice cruise in 4th. Oops forget this is the inliners board
