Nice find. Very cool to see that straight six in a doghouse. The width factor makes the Cummins seems like a good idea. The manifold mounted turbo on the 6.2 would likely require some re-working of the front frame members and doghouse (in what is already a crowded area).

Funny how this all started with a simple little magazine article. It certainly been interesting to hear everyone's opinions about this concept.

2tallpaul - as you progress through your conversion keep us all posted (with pictures if you can) of the conversion process and your results. Obviously from this thread more than a few of us have contemplated this conversion and would be interested in tracking your progress through to completion.

Was browsing ebay motors and saw this. Not sure what the difference is between the 6BD1A and the 6BD1T, I think the 6BD1T is what AS used. Maybe one of you motor experts could help me out. Not sure if it will work but the price isn't too bad right now, he also has a brand new 6BD1A available. Do the Isuzu diesels have the same motor mount placement as the 454 or would you have to make your own?

I think the 6BD1T is turbo-charged and makes quite a bit more power than the 6BD1A

The one part of the cost/benefit equasion I did not see above is the cost of the 2 454's replaced at 250K miles each as opposed to the 500K you should be able to get on a good diesel BEFORE IT'S FIRST OVERHAUL!! No kidding-I have a Mercedes Benz diesel 300Turbo with 400K on it, doing 100miles round trip to work and back every day!!

At the risk of being forward, if there is enough interest in doing this, and some unanimity in terms of engines desired, why not do a group purchase? The price should come down buying more than one engine, cruise control, etc. I have to presume that is what Airstream did when they first had the diesels put in.
