One of the HFT choices for your combo is the bigger Summit cam, which is hard to argue with for a variety of reasons.
Two other “name brand” options are the Crane H278, and one of my personal favorites for that particular type of application for the BB Mopar........ the Crower 271HDP.
You could also have something custom done, but in that type of application, that Crower is tough to beat.
We put that Crower 271HDP in a 440 that we built for my Dad's street-only 1970 Coronet R/T. The engine build is very similar to OP's with Stealth heads, HP manifolds, "stockish"-looking aluminum CH4B intake. A 727 and 3.23 gears being notable differences from OP.
Literally could not be happier with the way the car runs. The power is incredible everywhere, but Idles with just the tiniest bit of chop so you can tell there is an aftermarket cam in there. Power brakes work fine if you have them.
