The big different in the 500 & 600 beside the torque rating, is first gear, 3.27 vs 2.87 and the 5 th gear, .68, .64, .82.
I bought the 600 because I needed the 2.87 1 st gear.

The low end torque that "your" motor makes will make a different in the trannie you need. Tire size and rear end ratio also play a big part in the puzzle. I bought 3 trannie's and 3 different motor before I was happy with cruis'in in my Cobra.

1500 rpms at 50 mph in 5 th, no trailer hitch jerk, and 2000 rpms at 70 mph. I have enough torque to cruise in 5 th from 1500 rpms to ?????

Any gear is a passing gear

Thanks for the link to the Tremec site.

Looks like you found the right combination for you ... 1500 RPM at 50 mph is almost like running at fast idle, that's impressive! I'll probably run a bit higher cruise RPM, as my motor will most likely not have as much torque as what you are running. As you mention, there are a lot of variables. Just doing some homework, so I get it right on the first go
