An Erod 6.2 with 4L65E automatic in a 1992 80 series is a great package. We generally run the stock (rebuilt) transfer case, but you can have it converted to part time 4x4 with manual hubs too if you would like. This Cruiser now has quadruple the HP, and double the torque when compared to stock. Oddly enough, it is now about 150 pounds lighter, has reduced emissions and increased MPG! This conversion is smog legal, and comes from GM with an Executive Oder number from CARB, and a two year warranty.
