went to some truck/tractor pulls tonight. Saw two guys with 6.7's pull, wow, actually pulled pretty good. One guy had wheels and tires and one guy had the stock 20's with some pretty mild tires. The guy with wheels got to about 270' can't recall what the other guy got. I was impressed, the only thing I don't like, the truck is too dang'd quiet! I was sittin right at the starting line and you really couldnt hear much past 50-100'
the two most impressive pulls of the night (IMO) were a nicely built 7.3 and a tuned 6.4 with stacks
...oh and pigeon toe'd duramax
