It would depend on whether or not the drive-line could handle the additional torque at low speeds. It can be done but may not be advisable. The engine develops peak torque probably of 1450 ft lbs at the 430 hp setting and probably 1550 at 470 hp.
If you normally take it easy on the pedal while in the field, it probably wouldn't matter. It won't make that much difference to you at lower speeds to have the 40 more HP. The electronic engines have more low end torque than the mechanical Cat to begin with as long as they are running right.

you got that right 52. that being said, as long as your driveline is up to it, your local detroit diesel dealer can turn that motor up- as far as 500 hp at 2100 rpm (if my memory serves me correctly). and they can turn it up to a straight 470 if you want. but you will have to take it easy in the field, as least starting out. And post some pics already!!! we need to see the new hibred ride!

I will get some pictures as soon as we get the truck home from the body shop, its in getting the frame sandblasted and painted and there was a polished stainless wind deflector on the cab that we are having removed along with the mirrors on the hood so with all that work it wasn't alot more to have the whole truck painted a litlle different blue, going to match the frame with a little different color blue instead of black so it should look sharp, here are a couple pics before, one in the shop and one of our 89 Freightliner, again thanks i really appreciated all your replies, great to have so many nice people here. Will the Kenworth turn as sharp as our Freightliner did?
