Twenty forward speeds and a motor still pulling at 2300 or 2400 rpm will really go.

My old boss has a 1986 pete 359 with a B model 3406. He put the fuel pump, injectors, and turbo off a marine 3406 on the engine and ended up with around 625 HP. It had a double over 13 speed, 336 rears and tall 24.5's. I have personally seen it run over 110 mph. We paced it with the LX mustang I had at the time.

Now why would anyone want to go that fast in a truck :?

But maybe then it's time to ask yourself if you should :wink:

There used to be a few back when I started driving that would do better than 122 mph. Some would do over 130 mph. There are still a few bull haulers who could probably do over 120 mph. I don't think it would be smart, but the potential is there. You would have to be out of your mind to go that fast in a big truck today. :shock:

ok 3.08 ratios, but what final gear ratios? I know those 5x4's had really long gears in the final gears. I'm assuming 11r24.5's.

Also, I just don't see that kind of power being made. It takes about 200-250 hp at 60 mph, it would take easily 4X as much at 120.

And... to top it all off... not a single truck tire is rated for more then 75 mph.

There are some steel haulers who used to take 2 loads at the same time so that they can get twice the pay rate. Not only is it dangerous, it could cost you dearly should you become involved in an accident. I don't over load my equipment. If I can't make money on something without having to over load my equipment, I figure it is too cheap and that I don't need to haul it.

I was offered an attractive deal that was to start with a dead head of more than 1,000 miles. The load would have been about 9% above what I usually do, under permit, and would have been legal, within the permit limitations and axle ratings. Just a little beyond what I normally do.

I once hauled a die for casting aluminum from Cleveland to a little south of Appleton, WI. The shipper was Alcoa, and the die would cast landing gear struts for commercial aircraft. Under the permit, None of the axles could be over 20,000 pounds. That meant 4 axles at 20,000, and the steers at 12,000. Like Gman said... 92,000 pounds. If you want to go beyond that, you'd better have more axles.

I drove an old 1985 Freightlier that the owner wife had gotten up to 130MPH, (but don't tell her hubby she always say) Fastest I got it was 90, and slowed back down after passing the mile long line of trucks in AZ.

last week i heard on the morning news they caught a guy with a load of lawn fertilizer at 152 kph on the 401. He said he was trying to catch up to his buddy a few mins in front of him. Impounded the truck & that would fall under the street racing laws too, anything 50 k over. 152 kph would be about 90 mph.
