Spicer 5 speed will do - if ratio between 3rd and 4th is an issue - you can usually go up or down one size on the tire (9R22.5 to 10R22.5, 11r22.5 to 10R22.5) without issue to get that sweetspot where you want it. Even low HP diesels (170HP or so will usually have 450+lbs/ft of torque.



I am seriously considering shortening/bobbing a fullsize bus. Compared to cutting out a dented roof of a passenger car, cutting out a clean roof of a donor vehicle, welding it in place... cutting out 2 to 8 feet from a fullsize bus & reattaching the rear section seems pretty easy. I intend on visiting national parks and doing some hunting and fishing from a skookie and that 8 to 10 foot rear overhang seems troublesome. Seems like cutting out 8 feet and towing a soft-top Jeep would produce a similar overall weight, only add about 4 feet of total length, and allow for a nice runabout to hit local downtown museums/attractions. Unless I find a nice 6 to 8 window shorty with midsize truck cab, I am likely to 'bob' a fullsize for towing.

Thanks For The Reply.
I'm not worried about speed. We live in the Midwest so mountains aren't an issue. We'll find the right fit.

That IDI 6.9 you're wanting is only around 330 lbs/ft.

Shortening the distance between the rear bumper and the rear suspension is not very difficult if the engine is not behind the rear axle.


Your problem is going to be the power package. The vast majority of school buses spend 95% of their service life on routes at speeds less than 35 MPH. It is rare to find a bus that has the power and gearing to go highway speeds. Add on 10K hitched on behind and you will be living in the slow lane all the time.



Most big HP buses are rear engine buses. But there have been a few buses with engines up front that had big HP engines. I have seen a few BB AA's that had Cummins 6CT/ISC engines and some Type 'C' buses with big HP DT466's.



You will want to find a bus with an engine with at least 250 HP. Anything less will mean slow speeds for you.


Good luck!

Hey Crew.
I'm only looking at front engine buses. As far as speed, when we tow the Military vehicle we never run over 50 mph if even that.
My biggest worry is trying to "bob" the back end in my shop. Just don't know if it's something I can do by myself. Not sure who to even call to have it done?
