what engine and transmission do I have?

[scootie]

Short and long of it is... I bought my 2nd bus about 4 weeks ago. 93 Bluebird 8 window flat front (what I call transit style) front engine. straight 6. with what I was told was a cummins 5.9 and I don't remember the specs on the tranny. drove it home 1 hour and it does 58-62mph on the highway.

I'm about half way through my remodel and the slowness of the thing has been in the back of my head, but I'm in so deep with the remodel that I have just forgotten. Anyway while I was under the bus working I took some photos of the badges on the transmission. can someone shed some light on this for me?

found two: one is possibly a serial #93039712
since it's a 93 model and it starts with 93, I/m guessing it's stock, never been replaced.
2nd badge has block letters "spicer" SN 20098A
029CA104-1x
ratio 4 78

hoping if it's just geared low, I can change our the rear end and get 10+mph.

as for the engine, how where would I find the info?
thanks in advance

That's a bit on the lower side for highway duty. If you want to gain a few mph, you could go higher.

imo 60 is pretty fast in a bus, my bus is governed at 62. front tire blowout scares the hell out of me, great mpg also.
