Hello I wonder does anyone have experiance grooving a chevy van g20 350/700 1989
Im thinking about buying it. Interested about possible fuel gain on it,
thanks.

Hi Markus, I don't ave any experience on this engine/vehicle combo, but find out what the induction is. Is it a Throttle body injection? (TBI) Cause if it is then several guys on here have been posting about doing the Groove in Chevy TBI units w/ great success. As long as it does not have a Quadrajet carb. then I think it can be grooved. Have a good one, TracyG.
