112 on flat, at 1250 degrees EGT.

There's more in it with the water, overdrive and 3.07 rear end.

CK- is that on the street, or rollers? You got an auxillary OD unit or anything, or just RPMs?

Fastest I've gone was following a bull wagon in eastern CO- got up to 98, and he was still leaving me behind, so I dropped down to 80. 1993 C&C with a 18ft trailer, 3.54 gears.

Rumblefish, your pickup will go 90+ in 4th.

roger that. i only took it past 75 once until i changed the right front tire. i blasted it up to 105 with an empty trailer on the way to georgia to get my newest 4wd. it was on a new stretch of road just inside the GA line, about 2am, and the wife was asleep.

oh btw, i got 15.3mpg, loaded, crossing the rockys, trying to keep a steady 67mph, but running more like 70-72 due to traffic. i was passing semis and never had to pull it down to 4th gear. i was quite impressed.

I've had mine up over 100, maybe 105 or so. Just cruises, nice and smooth. Ask DP and GL, they've driven my truck, it handles awesome. 8)
Mine will go 93 or 94 in 4th gear too. ;-)

KTA, I think his price went up since he made the trip and got home with no breakdowns. :lol:
