Tim, it was sure good to see you, Mark, Dean, and Dave W. come down from STL for this thing. I run 3.31 Jag IRS rear, all special inside built by Mike Bontoft at Concours West. T-600 trans, .82 5th gear. But I run Hallett entirely in 3rd except for turn 3 where I drop to 2nd. Don't know what block you have, but if it is iron 460 then there is about 300#. I have all aluminum, and the 427 is smaller and faster revving, with roller cam and Erson roller rockers. Rev limiter is at 6K. Tires are soft compound replica Billboards, almost as sticky as slicks. Our rwhp are similar, I think about 420 on the chassis dyno. Hope there is a clue in there somewhere ...
