451, slightly reground Mini-Express (.652, [email protected]). 8" idle vacuum.
It'll idle a bit lower, maybe 1000-1050, but any load (like the electric fans going to high speed) and it spirals in and dies.
I would have deeper gears for a better SLR with the revs up, but I do more highway driving than stoplight blasts and 60 mph is already just a tick over 3000 rpm. If I do buy a TKX it will be hard to decide which low gear choice is better...
