Eddy,

City scales used for comerce do you really think they would not be certified? Yes it only refuse but the land fill charges for that so they have to be certified by weights and measurments. And since they to a tare weight even for smaller loads the inbound and the outbound scales have to be very close so that small guys with pickup trucks get charges fairly.

3540 and a stock turbo at 188 hp gives 18.8 lbs per hp and 16 lbs per ft lb of tq.

My guess is I have about 225 hp, 260 ft lbs tq.. Probably conservative so that gets me 15.7 lbs per hp, and 13.6 lbs per ft-lb of tq.

For multiplication including the tq converter 4.62 x 2.826 x 1.944 x 2.25 (converter) = 57.67 to 1

So actual peak tq is: 57.67 * 260 = 1500 ft-lbs.

I am surprised at how much more Bob's rig weighs since the V6 is supposed to be similar in weight.
