Cams Away!

Time to start researching a cam selection for my Duster 340.
The old grind, which really enjoyed the crap out of, was as follows:
Lift .450/.475
Duration 298/308
Overlap 79 deg.
@.050 232/242
This thing had a gloriously lumpy idle and ran like a scalded dog. My only complaint was that with a single plane intake, the idle vacuum was pretty low (under 10" IIRC) for power brakes. But that did not make it un-driveable by any means...
This time around I'll be using a RPM Air Gap in place of the Torker, and CR will be in the 10:1 range rather than the 12.5:1 pistons I ran last time around.
A833 4 speed
3.91 Sure Grip
650 or 750 DP
Suggestions on a good hydraulic cam for this combo?
And, yes...I like the lumpy idle.
