Bigger tires are an easy way to regear and you gain some clearance too. But yeah if its one of the lowrider buses then super high gearing may be the answer.
Post some pics of your bus, op!

Seems like you have smaller tires than I do and def want to go at least 4.10 or 3.73 like you mention.
Our speeds are much different for having the same gears.
10r that's what was weird to me is the similarities in powertrain vs top speed. Mine is dt360 190 @2700 with at 545 pushing 4.78 @2700 = 53mph, I would prefer 55-60 @1800.

Have you double checked that your speedo is correct?
Using online gear ratio calculators it sure seems like your bus would be good for a bit more than 53 mph.
Your bus should be capable of around 65-67 as it is.
https://spicerparts.com/calculators/...rpm-calculator
I plugged in the numbers.
4.78 rear
"1" for final drive since no OD
40 inches for rear tire diameter
2700 rpm for engine rpm

And also make sure the 545 is making 4th gear.. and not only running the first 3. Mine topped out someplace close to 50-53 in 3rd.

She is making 4 gears, warming bus now to make a check run on the Speedo which I admit didn't work until after I made all my repairs so maybe that's it. Will repost in a bit.

Pics don't do the drivers area any justice she looks new now, other than the mud and dog tracks.

Speedo bad

So the speedometer is at best a POS, yes 60-63 mph at 2700 per my trucks speedo. so I went from non working speedo to working but wrong, moving in the right direction I guess. Guess I can work to correct that while I install a temp guage on the tranny. Thanks guys guess Im in the market for a 4.44 carrier.

This may be simple to fix, it may be just your dip switched set wrong. Ultimately you need to calculate how many revs per mile your tires turn. Then multiply it by your rear ratio (4.7 and use the chart to set the 10 switches .. the cluster comes loose with just s couple screws and the switches are in the top of it .. I have tie full book of charts. Iím posting here what I think are the ranges youíll be in. I marked mine but Iím on 11Rs now and had recapped 10r previous. I used an app called speedometer on my iPhone which uses GPS until I got it right. If you determine you are outside the ranges I posted I can look others up for you

Here is the section in the tach switches . It is based on the number of flywheel teeth.

For mine I set it to 011 for the international engine and it works great.

I should add if your tach comes and goes it could simply be metal on the sensor.. when I swapped my trans out I found metal shavings presumably from the flywheel and road grime on the sensor.. itís magnetic. I cleaned it off and my tach doesnít jump around anymore.

Progress on Rover

It's been a minute since a post, Bus is now an RV, easy to do in Arkensaw. Windows, fantastic fans, A\C, 12 volt and 110 wired ceiling done and drivers wall. I manufactured all my wood siding as that took a once I finish the passenger wall in will mount my black and grey tanks and build out my garage as start building the interior out. I also found a RV propane tank which I've got to mount. Since the bus came from Rover Arkensaw, we shall call here "Rover".
