Re: C30 dually rear diff gearing options help please
I guess the 235's sound good.
For those with a relatively stock 454, If I didn't mind paying for the gas, and didn't mind the louder noise, how many RPM's is comfortable for the engine to do all day on the highway.
I just don't want to send the engine to an early grave. I'd like to take good care of it, so how many RPM's could I do all day on the highway without doing any damage, and with the engine being happy about it all?
thanks
