True statement about the V-1650-3 vs the V-1650-7. However, the power difference was not that great and the B/C was still faster, even with the earlier engine. If properly done, the B/C should be at least as fast as the D model, certainly not slower. As mentioned by Lt.Wolfe, there are the additional factors of the drag from the bubble canopy and the extra weight of the D model. (Although drag would have a much greater effect than weight on top speed.)

I've never really flown the Mustang III version. Is it true that it's the fastest ? I always assumed that they simply re-labeled the B/C version and that the performance would be the same. Very interesting, I'll have to give it a try.
