I don't think so, go to the website see all the different models of school buses he has. I called him to see if he rear end for my bus, I told him I had 586 gear ration and I wanted to lower the gear ratio down to the 444, he said that most all GMC Blue BIRD Buses
came with that 586 gear ratio
with 8.2 Detroit engine
. He said the 8.2L
sweet spot is at 3000 rpm also you get good fuel mileage at 3000 RPM
and with 586 gear ratio. he talk me out of buying another rear end.
This last weekend I made my first trip with the trolley, I travel 55 mph sometimes 60
and the engine ran great, I have to do something to suppress the engine noise inside of bus. Does anybody got any ideas on how I can suppress the engine noise?
I know one thing that this 8.2 Detroit
can run circles around 6.9L International
60 passenger school bus I bought brand new. I had to put a 6.9 rebuilt engine
in the bus at 20,000 miles, then at about 50,000 miles the engine started pumping oil out of the exhaust pipe like it did before with the new engine from factory. This time I went out and bought a 7.3L International
with no turbo. The 7.3L engine
was little bit better on power than 6.9L
engine was. The bus had 145,000
on it when I got rid of it and still had the 7.3L engine
I put in.
