Will this Cummings fit in my 72 Prevost, it currently has a 8-71 with an Allison. Just asking as this truck us being parted out locally to me. Thanks, Fraser
Good running big cam cummings
855 cubic inch
Asking $2500 or best offer
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
Yep the tag creates problems for you some change the the tag to a 94 model and up I have a friend that installed a M11 in his Prevost lots of work redoing the original tag for the engine to fit
good luck
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?"

That is what you get with the spell check Dallas LOL
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....
Don't worry about it how do think I know about the spell check thing lol
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.

No offence. I appreciate a little jab, it keeps my mind mind young.
I'm sure you must have something there that the Cummins will fit into....
As a CUMMINS stockholder, I must protest that mistake in spelling. That's ok we all make mistakes BUT DON'T LET IT HAPPEN AGAIN or I'll scream. :)

Ahh, but once again, Cummins is Cumming to the top. LOL
To bad, a Cummins Big Cam will run just about forever.
I'd make it fit... but thats just me
Even though the ISX Cummins is a 15 liter compared to the Big Cam being a 14 liter, the ISX is actually a shorter engine then the Big Cam. Hence the ISX would be an easier fitting engine. Personally have always thought the NTC Big Cam engines to be junk-just don't get the longevity out of these engines that you can from a Caterpillar 3406B or a Detroit Series 60.
When I was driving, I ran into an owner/operator that told me his overhaul strategy with his Big Cam 3 400hp. At 200,000 miles, he'd overhaul the back two cylinders; at 400,000 miles he'd overhaul the middle two cylinders; at 600,000 miles he'd rebuild the whole engine. In this day and age-that engine would be toast compared to all the new electronic engines going sometimes over a million miles before any mechanical overhaul. I had one driver come in and tell me he drove 150,000 miles a year and changed his oil on his Series 60 4 times a year-or every 37,500miles! I also asked how many miles on the engine he had an said 1.3 million without rebuild yet! Guess I couldn't scold him for lengthy oil changes-could I! Good Luck, TomC
