Why?By mid/late 1942, Mustang can get the Merlin 50. Yes, not the 2-stage version, but better engine than the best 1-stage V-1710 the Mustang ever got.
The Merlin 50 is a Merlin 45 with a different carburetor. Single speed
If that is all you want stick the V-1650-1 two speed single stage engine in the P-51s, of course that means that there are fewer P-40Fs and Ls.
