Thanks Grigg and Jerry. Your comments have helped me at least get a sense of what its worth. Grigg, you may be right about the 4.57 still being too low gear. With the loads I sometimes haul or pull, the 5.13s were about right for my tired 235. With the additional power from the newly installed 261 I know I can use at least a 4.57 gear. Maybe I should reconsider and look for 4.10s like everyone else. By the way, I don't plan to use the entire HO52 axle, just the center section.
