Here is the dyno. I do not think 300 lb-ft at 2000 rpm is all that bad. Granted that is 142 less than the peak, so it is far from flat. However from 3000 rpm up it is fairly flat. Most builders will not dyno down to 2000 rpm and you rarely see those numbers.

PS: This is from an article Twobjshelbys provided the link to above. I believe this was an independent test, not Ford data. Also note that it stated headers were used. Likely no belts.
