There are lots of smarter guys than me , living a lot closer to you; and like I said I got no experience with BBs, never mind strokers, nor cams as large as yours.
Waitaminute!
I just remembered something from 20 or so years ago; I know three fellas in nearby towns, that had ugly-idling engines; two Hemi's and a 440, that I managed to get the stink out of.
The Hemi's were MP crates, and I hesitate to say this but they were no trouble.
But that 440 had a wicked solid-lifter cam in it, and she was a challenge.
If you lived next door I'd be giving it my best shot.
