John,

How about a Mallory 4309? I run one on my car.

You could have the reg referenced to manifold vacuum.
15 inches of idle vacuum with the reg at 2psi, would give you 9-10 psi at WOT.

Or you could replace the spring with a softer rate and get 2-8ish psi instead of 3-12 psi (Mallory factory spec).
