[doug tenney]

Hi John. With stock Mc9X's, we typically run 9/64 (7.1:1) or 10/72 (7.2:1) at Oreville and the other NE tracks. That's pretty conservative. If you're heavier and/or have a well-tuned setup, you could go as deep as 9/68 (7.56:1) or 10/76 (7.6:1) with a Mac.
We ran our stock US820 for years at Oreville at around 10/69 (6.9:1).
See you there!
