Which TKO 600 to get .64 or .82?
This is going behind an aluminum CS 427FE motor in a brand new superformance chassis. This car will just be for weekend driving and for having fun. Tremec says 90% of their sales are the .82 I have had several installers suggest the .64 for highway driving and several say the .64 lugs or feels bogged down on the interstate and recommended going with the .82 I have also considered going with a 6 speed. Thanks in advance for your input.

Reason: Had ratios backwards
