Hi all,
I've found through the brochures, the first couple of years list the 455 with 212 hp @ 3400 rpm and 344 ft-lbs @ 2400.

I can't seem to see anything about the 403.

I'd appreciate any numbers and comments regarding how people feel the power and torque originally mentioned made the motorhome roll along, and if improvements have been made, what was done and what the results were?

I know a lot of people seem to have chosen to change final drive ratios...I believe for towing reasons more than anything?

Fuel mileage seems quite consistant...around 10 to 14mpg, has anyone made any dramatic improvements to this?

Any info or opinions would be fantastic.

Thanks everyone,

Gord
