I'm currently working a good deal on it. I will post pics when I bring it home from the shop.

This will be the drive train for my Four Season Prime.

I meant to change it over yourself. That is built from the factory with everything required. It may not be as bad as I think, but you need to add a TPS, and if the trans came off a vehicle with an electronic engine, you would likely need to change the software in the TCM. Just speculating but there is likely more to the swap than meets the eye.

Thx

I look forward to digging into it and learning as I go. I will post as much info as I can.

Nat you scored a real good drive train. My All American has the same drive train, 8.3 with MD3060. I am also running 5.38 differential gears which in
5th gear (first overdrive) engine RPM is 1800. If I can open up 6th gear it
will bring RPM down to 2600. The Wanderlodge owners group had one of the members swap an 8.3 with a MD3060 into a Wanderlodge with real good documentation and pictures. My 1996 AARE has air throttle with TPS on it
and a mechanical engine. Make sure you get the wire harness, computer,
relay box, throttle pedal and controller. Computer is a $750 item by it's self.
Forgot to mention the Wanderlodge was built on the same chassis as the Bluebird All American and Wanderlodge had the distinction of only having one death in a rollover accident in 50 years of production.

Thx, Great info.

This one is also geared 5.38. Every one of the rear engine pushers at our shop seems to be geared 5.38. I'm getting the only one with a MD3060. The rest of the pushers are MT643's.

I was a bit concerned about the gearing because my other bus is 4.44. But now that I know it will only be turning 1800 RPM, that will be fine.

Looks like I was posting while half asleep last night the sixth gear engine speed would
be 1600 RPM not 2600 at 60mph/100kph. Also my tire size is 12R22.5. The 8.3L has
max torque at 1300 but they say you shouldn't run them at max torque for any length of time and the best economy is 200 to 300RPM over max torque.

All good, I knew it was a typo.

That's great info about the economy.

6.9 is all mechanical. Redline, depending on the pump is either 3300 or 3800(6.9 vs 7.3 pump) I'd like an automatic, but all the ones I've seen are $2000-$3000 just to get the transmission let alone the computer to run it. Plus, I'd like an overdrive so if I would swap transmissions, regardless of an auto or manual, it'd have to have OD. As far as manuals go, all the really desirable manuals(RTOO9913, spicer 6+1, Fuller T34) are either expensive(1500 bucks for used, unknown condition) or are obsolete.

I priced some different options over the weekend:
1)The torque converter for the at545 would be about 350 bucks, couple that with used 4.78 rear gears at 650 and I'd be at 1000(about the most I wanted to spend)

2)With the spicer 6543(.79 OD) that I found. 250 for the trans and clutch, leaving me 750 to find and buy a clutch pedal/linkage assembly and shorten the driveshaft.

With the 4.78 gear, and new torque converter. I'd cruise 65mph at 2600 rpm. With my current gearing(5.57 not the 6.50 I thought I had) and the 6453. I'd cruise 65 mph at 2400 rpm.
I'm leaning towards the manual at this point because of the lower rpm and the increase in reliability. But before I buy it, I'd like to source the pedal/linkage assembly.

At the most, I'd want to spend a grand on this undertaking. I don't drive it thousands of miles a year, and the combo I have isn't all that desirable(6.9 w/ at545). So if it costs any more then that I'll just live with it and hope it doesn't blow up. I just can't see spending 2-3 thousand on upgrading what I have when newer busses are about that much. At that cost I'd just as soon buy a newer bus with the gearing that nat and dragonpop have, swap the stuff from my current bus to the new, and then sell my current bus, then blow a bunch of money on an old bus.

True if the bus is not converted yet.

If the bus is already built, we must swap what ever is needed.

I'm not sure you'd get a 6.9 up to 65, especially with an OD.
