Here's an EXTREME example of startability - getting 141,000 lbs rolling:

As soon as he's rolling in a stead gear, a gasser of equal hp could do euqally as well. Let's say a 640 big block pumping out 600+ hp.
But now we're talking gradability, not startability.
So you kinda disproved your own point. Torque gets you up hills. HP decides how fast.
If the 600hp big block is pulling a load that requires less than full torque input to maintain speed (i.e. Able to accelerate), it will be able to accelerate faster, in general than the 400 hp diesel. Once the grade or load requires more than the 500-600 ft lbs that the gasser is able to produce (assuming right rpms for top of torque curve), the 400 hp diesel will walk it because it's still able to maintain speed.
Remember without torque, there is no horsepower.
That's an impressive pull for that pickup though.
