Looking to replace my C10 truck's 2.73 gears with 3.23 or 3.42. Engine is a mild 350, trans is a non-lockup TH350, tires are 29" tall.
Sure, I can do the RPM calcs, but just want to get a feel from guys who are actually running that combo. What's it like at 60 mph and then 70 mph? Not that I drive the highways a lot, but don't want to be running in the slow lane at 55 when I do!
I may someday go to a 700R4, at which time highway RPM won't be a consideration. In that case, 3.42 gears should work well. But if I stick with my TH350, 3.23 or even 3.08 probably makes more sense. Thanks.
