Plus cranking them up past 450ft/lbs of torque is easy and not really stressing the engine.Ever since Leroy did the isuzu burb I've wanted a 4bd1 in a square body 4 speed dually. Nice sounding and stout built little engines. I mean they have cylider liners and aren't throw away design engines!
He'd mentioned the vibration earlier in the thread but stated another reason for going back to the 6.5. The Isuzu's vibrate less than the 4BT but will always vibrate more than a v8.Because a 7.3 swap would be the easy button with parts that fit out of a junkyard. The 1988 7.3 (Banks Turbo) crew cab down the road has 1/2 million miles on it and only the 2nd engine. Got to watch the coolant so it doesn't eat the liners...
Didn't Leroy remove the 4 banger diesel (aka undo the swap) due to excessive vibration?
The highest dyno'd numbers I know of are over 900ft/lbs of torque on a Cummins 4BT. A guy with the Isuzu 4BD1T who was pushing for high power blew the head gasket at over 65 psi of boost, running a compound turbo setup with a hx55 as the low pressure turbo. Went to ARP head studs and still driving it.Pretty sure I read that there are some running close to 400HP with the upgraded ip and turbo. Thats pretty impressive for a 4 banger.
I know I read a guy saying he had a head with firerings. Might be the same guy.The highest dyno'd numbers I know of are over 900ft/lbs of torque on a Cummins 4BT.

Yes, I have a c-6 for certain. I have old knees and want to stick with my automatic. I did remember something about many automatics not being able to handle the torque of a diesel. I really needed something cheap and easy. I guess a big diesel like what comes in Fords would be the easiest. I think it would take a lot of driving to spend the amount of money it would take to buy the diesel parts. thanks for the reply though.Are you sure you have a C6? 92 I thought was E4OD as Ford came out with there HD OD in 88. And I'm 99% certain the bellhousing pattern is different. Ford wasn't like GM with a standardized bellhousing pattern. As to which engine, for a 4 cylinder the Isuzu 4bd1t would be my 1st choice. 2nd chpice would be to shop around for a 4bt Cummins 3.9l isb backed by an allison 1000 5 speed. I've seen complete takeouts ready to go out of bread vans go for under $4K.
