Another 4.6 guy over here.
My 0-60 is closer to 10 seconds I think !
Also on a 6" lift, and running 3.73 gears, true 35" tires load range E (heavy SOB's !) 18" rims, and no real power mods yet. Too many other projects going on right now.
If its dry when I get home, might hop in the truck to see what I can get. Been awhile.
