    X3, That would be an awesome setup, I wouldn't go much bigger than that in a 4.8 either...bigger isn't always better.

    youll need a bigger stall with that setup in a 4.8. also i would run a steeper gear. that combo wont run as hard as it needs to be with that near stock stall and 410s

    4.8 is a motor that lacks lowend, youll need a large stall and gears to help it get to where it actually makes power.

    it ain't that I'm too big to listen to the rumors, It's just that I'm too damn big to pay attention to 'em..That's the difference
