Hi all, this is my first question, I have a 70 k10 with a 12 bolt rear 4.10 gears, and 10 bolt front, I'm not worried about gas mileage as I already dont have any.... this is more of a mudding truck, I want to put 20x41 inch super swampers on, I currently have 38.5/39x16.5 I believe, it pulls like a freight train now, when I put on 20x41, will my acceleration decrease? also what would you recommend for the gears? sorry if I missed any info....thanks in advance
