Excuse me, I’m not a rear axle expert. What is the highest geared rear end/third member that was typically available for a 10 bolt 8-3/4 rear end b body ? Last I remember, I have a 2:73 or 2:74, something like that, lol !
I’m interested in looking into swapping out for a higher gear ratio for better highway speeds. For example, on a 70 mph road, it’s more practical if I do 60 mph because my car feels like it needs one more higher gear. At 60, it cruises at 2K rpm. But, to go any faster. I would need to hold pedal to the floor and keep it there.
What I’m wanting is to slip in another third member that would allow me to do 65-70 mph while dropping the rpm’s from 2K to 1500. I have a LA 360, 904 auto tranny. The car will easily exceed 60 mph, but I would have to be pedal to the metal.
