Any idea as to what the mileage will go up with the Chevy by, or down on the GMC by. Right now the Chevy is only getting 8 miles to the gallon. I'd like the chevy to be a little more drivable, I know getting rid of the full cam would help, but I love the noise. Any other comments on what the effect on performance would be? BTW, here is a link to pics of the chevy.
