350-450 Ft/lbs of torque.

That particular Isuzu engine is rated at 87HP and 166 FT-LBS of torque. It is a 235 cu in engine. The good thing about diesels is the ability to turn them up usually for either no cost or very little money.

I know that the Isuzu 4BD2-TC is rated at 135 hp, but I couldnt find a torque rating on it. They are a peppy damn engine though, and if memory serves, the 4BD1 is rated at 128 hp, so they are both good engines, and are capable of being turned up cheap.

I have been flipping back and forth on the whole altitude thing for awhile now, and I know of guys say slam and lower it, but I just can't see the big rattling diesel dually in the weeds. If it were going to be a big block truck, I'd be more open to it, but low and diesel just doesen't seem right to me. That leaves me with the dilemma about what to do about the rake. I went back and looked through a bunch of my saved dually pics 68gmcdually's extended cab dually and the blue Longhorn dually really stuck out because they have an all business look to them. Both of these trucks sit almost level, and IMO they look good that way.

I got the ol dually out today and hauled off a bunch of boxes and junk from my storage building (ya know, cause Santa has to put the toys together in there to keep from waking the kids!). When I got through, I threw the trusty ol floor jack under it to get some ideas. I bought a full set of 6 almost brand new tires that are a good bit wide and taller that what I was running, so I put those on and and jacked up the front to make it sit level. From the current height I'm going to have to come up about 3" higher in the front to make it level. I like the look of it that way. I'm thinking about buying a new set of 80's Diesel C-30 front springs since they seem to be about the heaviest ones made that will easily fit under my truck. I wonder if it will be enough? I may have to run a spring spacer as well. I am definitely going to be spacing the front wheels out a couple of inches also.

Not much of an update I know, but it was nice to get it out and drive it around a little.

Glad that you used my truck as a reference, my truck normally sits fairly level. Lots of people ask me why I didn't bag it, but I built my truck to tow the car trailer and the house trailer and too me it wasn't worth the money to get it down that low and still have it be able to handle a 30' house trailer or our float with a car on it.

Thanks for the inspiration. I think I am going to try for a stock bed.
