Short bus/long trips TDO 3-17-04  
We own a 1989, 29 passenger bus. It runs on gas and houses a chevy 454. Our intention is to drive it on long trips 600-700 miles at a time. The bus doesn't have an overdrive so it raps out pretty high. It will do 70 easy on the highway, but it runs at around 4000rpm. Is this a concern for longevity of the engine. Is there anything of reasonable cost that we can do to lower those rpm's

It all sort of depends upon which chassis your bus has.

If it is the P-series GM/Workhorse chassis, there are a lot of overdrive/underdrive auxillary transmissions on the market. Most of them work fairly well at lowering your cruise RPM's.

If you have a larger chassis about all you can do is change the rear end ratio.

As far as longevity goes, the 454 was never known for going very far. They tend to eat up cam shafts.

Are you sure it is a 454? In the medium duty chassis the 366/427 engine was what came from the factory. Those engines are good for at least 100-150K without any problems, even if you run them hard at high RPM's.

Good luck.
