oh, my mistake, thanks for clarifying.

Yes there is also a suburban 2500, probably has the 80e. I saw a suburban 2500, had the 8.1L engine haha, so I'm sure it must have had a bigger tranny too. I wanted to buy it, but realistically, I have no plans for any work that the 1500 can't do, and so didn't want the higher maintenance and repair costs of something with a 500ci engine and matching drivetrain.
