Re: New rear gears for 65 230 manual, suggestions?

Great, thank you all. I also have a 85 K30 Dually 454. It has almost the same issue, but its an auto (THM400). It hits about 65 and thats about it. However with it, the higher the MPH goes, that faster the gas gauge drops. I think it will tow a house if there are enough gas stations along the route.
Maybe 3:42 would be a good middle ground for the 65.
