Chief has started an interesting thread in the new Big Bolt forum about re-powering larger trucks with later diesel engines.
I've put an LT1 350 EFI engine in my 3/4 ton and plan to tow a 25' fifth wheel trailer with it. I think it's going to be enough engine for the job, especially since I will be towing only 2-3 thousand miles a year and running light the rest of the time, and I expect to get pretty good mileage with it--maybe in the 17-18 mpg range.
But I wonder...what if it is underpowered when I get on the road with the trailer? What's the best option for more pull? I'm sold on computer control for mileage and extended engine life, so I want to stay with EFI of some sort. I could change over to an EFI big block, or...
My brother-in-law, two nephews and a couple of friends all rave about their Dodge trucks with the turbo Cummins diesel engines. My understanding is that later models of this engine are computer-controlled and get great mileage as well as big hp and torque. Does anybody do wiring harnesses and chips for these engines with transplants in mind, the way they do for GM EFI engines? I had my choice of several places to buy a harness for my 350. A turbo Cummins-powered AD pickup would be some kind of cool, I think....
