Like the Caterpillar 3406/C15/C16 and Detroit Series 60, the Cummins (NO G) Big Cam is a big block truck engine that is much taller then your 8V-71.  You'll probably have to make a dome above the engine protruding into what I assume is your bedroom to make it fit.  Plus it is a heavy engine-pushing 3,000lbs.  While a good engine-I think it is an overkill for a bus.  The better engine would be the Cummins ISM that weighs in around 2,200lbs (actually less then the 8V-71), is about the same height as the 8V-71 (although longer) and can be rebuilt up to a 500hp and 1550lb/ft torque.  The ISM is an electronic engine.  The Big Cam is a mechanical engine.  Good Luck, TomC

 The  years before prevost put 60 series in their coaches the tag axle configuration prevented the use of longer engines in them also.   Dick Eagler and hard headed ken can fill you in on that better than I.  I know it would involve Major mods.   Bob

I really appreciate your help on this, the price was right but I was unsure if it was the right engine for me. I'll pass on the Cummings and keep enjoying the the sweet sound of my Detroit..

What kind of engine is a "Cummings?"

My deepest apologies to all the scholars on the site, I used the cut and past from the sellers advertisement. I guess I was thinking about comings and goings, but that is another subject. In my defense Cummings is in the spell check when you type in Cummins
In the future I'll be more attentive, LOL, I do appreciate your help, you save me from having a big Cummins in my car barn. Thanks again....

Sorry, I was just picking on you. Clifford is right, but my way around it is to add the correct spelling to the spell check. Right Click on the "misspelled" word and click on "ADD"

Of course, if you are an internet exploder fan, that may not work. My experience is with Firefox and using Linux.
