NOT the usual cam advice...

I'm interested in people's thoughts on this one:
The build so far:
360 roller motor, freshened up but basically stock. No head work other than cleaning up the ports and port matching. TBI, currently factory issue (yeah, I know all the gripes; but it serves me well and has been trouble-free. Someday it may get changed out, but not right now. And yes, I know the factory electronics aren't very forgiving and limit my options. That's why I'm posting). 2:76 rear, but with a low 1st 32RH, stock lockup convertor; manifolds and dual exhaust. Daily driver/road tripper early A wagon.
What I'm looking for:
I don't give two hoots about a lumpy idle or how it sounds. I need something that idles well, has good bottom end, smooth power band and plays nice with the F.I., a little better performance across the board would always be nice but not looking for a tire fryer. It's the family cruiser...
My current thoughts:
1.) Just stay with the factory 360 cam, and call it good.
2.)Throw in a factory 318 roller cam (has marginally improved timing events).
3.)One of the above 2, and bump up the rocker ratio.
4.)One of the RV type grinds that everyone offers for these, being basically a truck motor...
5.)And of course, I know: call and talk to any of the various cam grinders and get their input on a custom grind...
Any feedback on what you may have done, what kind of results you may have had with similar setups, or recommendations on what has worked well for you is more than welcome; just remember, I'm not trying to set the world on fire with this one.
