My rear end ratio is 3.46:1 I am unable to afford changes to the wheel size or tires and don't want to change the rear end ratio. I will be doing occasional freeway driving here in SoCal and occasional longer trips on the freeway but the vast majority of my driving being simply around town.
Which TKO 600 should I get .62 or .82 OD and why in your judgment? Thank you in advance for any input you can give me on this.

Tim,
You ought to do some searches on here and other places about TKO shifting problems going into third gear. Another good search is TKOs that have locked up in gear forcing you to drive home in whatever gear you parked it in.
Both are real problems and take a lot of the driving fun and turn it into maintenance fun. Driving fun is preferable.
Tremec has a very good transmission in the T56 that does none of the above and if you are after brute strength then check out their new T56 Magnum that they rate at 700 ft/lbs of TQ.
Although you can change once the trans is in, if it is not in yet the T56 might just be the better choice ...
