Isuzu Diesel swap
I have searched the internet for some time trying to find information on the various isuzu diesel engines. different years, model numbers, various specs etc... but have not found too much info. I am looking at a possible 4DB or 6DB swap into one or two of my rigs in the future. My cousin has a 6DB in his '79 chevy with DRW and it is a pulling machine, and with no overdrive he gets around 19mpg. He also has plenty of room for more power if he wanted because no matter how heavy the load or how steep the grade he can hardly produce any smoke at all. And probably most appealing, not a common swap and they are so quiet compared to the cummins. I have spotted a 4DB on craigslist but it is out of a 1980 GMC, and without knowing any details about the engines and specs I am hesitant to pull the trigger. Any information or even where I should concentrate my research would be greatly appreciated.
