Based on the limited info,I'm comparing this engine to another 351-W I know of with very similar specs, dynoed at around 325 HP at the flywheel......assuming your engine makes 325 hp at the crank and it made 280 at the rear wheels, that is a 13% loss,which would be outstanding......
I'd say for what you have,those numbers are in the correct ballpark..
Switching to an air gap dual intake and 600/650 double pumper and a good tune, I'd bet another 20 to 35 hp would be possible....
