Russ,
Your comment comes up frequently, and the only answer I have is the gear ratio differences between the T56 and the TKO along with my lower rear gear ratio. Compare the T56 to the TKO and you will see a little lower ratio (normally) in the T56 vs the TKO in the first three gears and a closer ratio (normally) between 4th and fifth in the T56 vs the TKO which all contribute to a little quicker acceleration through the first 5 gears.
If we were both running the same overall gear ratio, I doubt there would be much difference in acceleration with both of our engines coming off the same dyno making very similar horsepower and torque numbers.
This information is what I believe the initial thread question was about. I hope we have helped answer the question.....although my combination works for our horsepower and torque curves it probably wouldn't work as well with another engine.
