I am looking at an older 65 passenger international T444E with an AT545 transmission I think it was a city bus not highway.
What kind of governing would I expect to find? What speed?
Could this be regoverned?

Expect 45-65 mph depending on gearing etc.
In a full size bus the 545 transmission is a dog.

The rear axle ratio and tire size are what determine your final gearing.

It should be on a metal tag on the rear axle.
If you don't have the bus, ask the seller

if the bus has sale listing has a VIN, and its a thomas, bluebird, or international, tyou can call the manufacturer and they may very well be able to tell you the specs of. the bus as it was built... (engine / trans / tires / rear)..

Get the VIN number and the manufacturer can usually tell you how it came equipped.

There should be a tag on the rear end its self that will tell you the ratio.
Mine has two tags that are both on the front top where the drive shaft enters.
Yours might be somewhere else like on the back end?
If you can't find a tag then there are a few ways that we can help you figure it out.

with a 444, 545, and outdated tire size it doesn't sound terribly exciting, unless its really cheap.

It says (Splicer Ratio 4.44) Is that enough info to figure out the top speed?

Yeah.
Expect just over 55 mph at 2500 rpm.

running a T-444E at maximum RPM of 2600. for prolonged periods in the hot summer can often cause over-heating.. so be careful when thinking about it..
ECCB has it right.. that will be a 55-60 MPH MAXIMUM, bus on flat ground..
