Not Ranked
The rpm's sound great @ 80 mph! But do you know the actual rear end gear ratio?  Like 354:1 or 331:1 If the actual rear end ratio is not listed in you paper work, mabe you could ask the seller. As He said he was the original seller/dealer, hopefully he will have that info. As I plan to use the same trany you have. Knowing the rear gear you now have, will help me make my final rear gear choice. Thanks m8!
