Recommended 8/34

Thanks for the reply. I have 3 center sections but are 741 case, ratios are 2.94, 355, and 391 all open. I have considered swapping the gears, say the 355's over into another case that I was looking at and using the sure grip unit. Both of the other cases have really low gears, and I'm not real keen on twisting the motor on street cruises. I figure the 355' may be kind of ideal for both purposes behind a stock motor. I did find some info on those 2 diffs. but I wasn't sure which would be the better of the two and easiest to rebuild if needed. I'm a novice so I'm not familiar with those cases.
