No I don't, but as I remember it the 2800 isn't all that wide and didn't make for a huge look to the nose.
It had a big spinner and afterbody for the intake like most racers, and a fixed area ramp on either side for the cooling air exhaust and the engines exhaust stack outlets arranged at the exit point for jet-pump like augmentation of it's escape.
The Mustang fuse is pretty deep and there was no difference in the side profile until the taper towards the leading edge of the cowling. The radiator scoop was of course deleted so it was a very clean profile. The oil cooling was done with a 0 drag boil-off system, and the wings were clipped at the production break at the second aileron hinge as is typical for all but two Mustang racers.
The hot rodded 2800 would produce about 3200 hp at 90 in hg and 3200 rpm and at the time would've been super competitive in the racing scene. Maybe it still would, as the Dwight Thorne Merlins put out the @ same hp but have the radiator drag. It would depend on the amount of detail to cooling drag, as it always is.
As for the military version, I never saw the NAA drawings. The ones my racer friends had were detail for the motor mount and such. I just saw the racer outlines and some cowling sketchs.
I was very lucky to have met a lot of the pioneers. Amazing that so many were involved in air racing, or is it?
