Hughes doesn't really offer an OEM replacement cam, but IMO this would be it. If anyone is looking for a modern version of the OEM 383-440 HP / 6BBL cam grind, Hughes has something in their Clearance section that would fit the bill: 215/223 @ .050", .470"/.506", 115 LSA, 3-bolt, $125 (Clearance price)
Compared to the OEM cam's 214/226 @ .050", .450"/.458", 115 LSA, it'll probably idle the same and pick up the torque across the curve. I wouldn't expect it to change the working RPM range much, though.
