Cam and carb suggestions

I've heard of this cam:

.444/.456 lift - 276/284 duration - 52 degrees overlap - 112 degree centerline

Supposedly an old Mopar grind...maybe even a specific 340 auto grind?.. Not sure. The lift looks ok ..but wouldn't mind seeing a 484/495 with that duration ....but maybe with a 108 centerline or 110 max for my 2600 stall and 3.54 gears? What say yee?
I'm close enough to a custom cam grinder as I know that would be a one-off grind.
