Yeah - they'd put an '80 in a 2500 Suburban or 2500 and 3500 truck, but I don't recall GM putting those on engines smaller than 6.0Ls. I know even then, there were LS2 running around with '65s, not '80. Those things weigh more than 200 lbs. and suck a good deal of power. The gear ratios are also less aggressive than '60s, so I imagine one of those behind a 5.3L would bog it down pretty good (I mean bad). Maybe the
did put an '80 in there though. I think if you look at the RPO code tag in the door, and look at the "MXX" codes, you'll see like M30 in there. You should be able to decode those on-line and determine what was
supposed to go in the Tahoe and what it
should have.
