Ive never drove a 4.6 but like any small motor, put lower gears in the butt and it will help, likewise 3.08’s with a 351 makes having a V8 almost pointless. I have driven a 5.4 3V. It was a 3/4 ton reg cab longbed, 3.73’s and was impressive. We did do the spark plugs (it was dads truck) and 6 of the 8 broke, Dad anticipated the issue and we had the extraction tool kit on hand. Was still a pain. That truck is still around but its a rust bucket. A ‘05 XL, must of been a fleet vehicle for a landscape company, had a plow on it , no extras, plain steel rims.
Im thinking about a bigger truck myself, It seems too good to be true, a 96 1/2 ton shortbed reg cab, 4x4, 351 auto, black. $1,000. It’s tempting, Ive not had a V8 in years. It looks good (from the pictures) and only has 120K (supposedly)
