This is a 7.4 liter big block. You don't find very many of these. There are 3 currently for sale in the US through autotrader.com at 9,999 to 24,995 when I did a search for any 1996 to 1999 models. There is also 1 other on KSL for about 4,200. These are rare Suburban. We replaced the engine and almost everything in there about 30,000 miles ago. We also had the transmission overhauled at the same time. It isn't our daily driver. I primarily use it for towing or camper trailer. It could use a tune up, but otherwise it is currently licensed and runs. It also needs new tires.
