Just finished a mess of things with the Grump (1990 Jimmy 6.2 Banks Sidewinder, 343:1 G80). Had the turbo rebuilt, replaced the crossover pipe ($340 from Banks OUCH) flushed the injectors, rebuilt the steering column (not as hard as it looks). Only issue was I had to dream up something to pull the pins, other than that, cake. Got rid of the clunky looking Banks filter box. Now he pulls really hard and sounds killer when the turbo spools up. He ain't real fast but sure sounds like it. Pics when I figure out how. Still a work in progress but he's rollin'
