Hi Chris,

As far as airfoils go, you might want something like an eppler 374 for a vendetta. At 12%, it is a good overall choice for turning radius, speed, and handling. G-62's are not supposed to be modified in the T-6 class and run with an open header. I'm not totally familiar with the top flight p-51, but a G-62 might be too much weight for your airplane. Try and keep it light overall, along with having an engine that does not stick out too much. Most of the t-6 racers are running an APC prop specifically made for the class with the G-62. I think you can call them up and order it if you want. Awhile back, there was an effort to start racing with webra 1.20's in the top flight T-6, which is smaller. The At-6's run a 15% laminar airfoil and are doing around 140 with the G-62.

note: typo corrected. airfoil should have been 374.
