Scott, having owned and driven both the 4.8 and the 6.0, if you were to buy a new 3500 van what engine would you choose? Any performance difference between the two? I guess a meaningful comparison would be worthless since the 6.0 was in the Baby Beast.06 Express 4.8l maintained as a slop bucket should be (rarely if at all). Just under 500k. 18-19 mpg.
