Hello all,


I am new to this site and not sure if this is the right place to post. I am currently having a bus sourced but I don't know much about engines and transmissions. Any information will be very helpful.


I am looking at obtaining a 30ish' flat nose with a rear engine. I do want it for mountain driving and from what I have read, rear engines are better for that. What I really need help with is the type of engine and transmission that would be best for this type of travel.

Welcome,

Unfortunately 30' RE's are a rare bird. A lot of them in the 37'-40' range. Most 30' "flat nose" will be front engine.

Thanx for the reply.


I'm not opposed to a bigger bus or a dog nose if necessary. I've read that a rear engine is best for mountain driving and is quieter. I do have someone sourcing a bus for me so I'm hopeful something I'm happy with will be found. I just don't know anything about bus engines or transmissions which is more important. Any info I can get on whats good would be a big help, that's where I'll start and basically find a bus around that.

If I were looking for an RE, I would want either a DT466 or a Cummins 8.3. For a trans I would first look for an Allison 3060 (preferrable with 6th gear unlocked), or AT643, or a 2000.
I don't think an FE handles the mountains any differently than an RE. I guess the RE's usually have the bigger engines, so that's why they're good in the mountains, but an FE with the same drive train handles mountains fine.

RE has a distinct disadvantage when it comes to cooling. For tough mountain passes its really hard to beat a rugged CE from a mountainous region.

I would have to agree with that.

I have a 37' RE with an 8.3 Cummins and MD-3060 in a Bluebird. It is my idea of the ideal skoolie drive train. One reservation. Most school buses with the MD-3060 have 6th gear locked out so you effectivley have a 5 speed. Owners of IC and Thomas buses have had some success getting 6th unlocked. Bluebird has not been cooperative. I have not seen a successful Bluebird 6th gear unlock YET. There are some third party vendors are beginning to support the MD-3060 and may be a good option for Bluebird owners.

I have owned two RE's and one FE.

There is NO doubt that FE's cool better.

My first bus weighed 42,000lbs. I did have some cooling issues on I-10 in AZ in August. I had to slow down and run with the slower semi's.

My current bus is not finished but I did pack it with my entire household and use it as a moving truck. Three mountain passes in mid to high 90's temp. No problem.

The RE's have been much more comfortable for me to travel in. Noise and heat are all 30-40' behind you.

How is it that a bus manufacturer, (Bluebird), can dictate what performance options can be had on an Allison manufactured trans.?

Seems that should be something that could be hacked without a Rocket Scientist degree???
