I would really love to see that Turbo in person. After now owning a Turbo Diesel Dodge which is really just a bigger version of out 258's... I'm in love with Deisels! I am determined to drop a Cummins in an Eagle without getting rid of too much of the original drive train... or at least keep it AMC. For instance, going with some AMC Wagoneer axles or something. The gears have been turning on this for awhile. I won't be pulling the trigger for quite some time though. Too many irons in the fire right now as it is. I'd be happy to be able to get Pat's Eagle and My wagon finished for the Meet though I have a feeling I'll be pushing it to get his done on time. At the very least his will be painted for the Meet and I hope to win a trophy with how purty she is this year! Might have to finish it and not let Pat have it back until after all the big local car shows are done around here, lol!
Just so you know, from someone else who has had the gears turning on just such a project myself. The full 6cyl cummins will not physically fit under the hood. It's to long. Been a while since I measured it, but i think it would be firewall to grill.
It's also several inches taller. So there needs to be some serious modification to get it to fit properly with the tranny and such inside the tranny hump.
And one last thing. I'm assuming you know this, but I'll say it anyways. Because the cummins is a diesle, the torque curve is much higher than a gas, and also at much lower RPM, if you bolt it up to an auto that hasn't been rebuilt to handle the low revs, it'l go bonkers lol
You probably know all this, but i just thought i'd mention what research I've done on the subject.
