If it's together and working, and is built the usual A V8 way with a V8 trans bolted to A torque tube...buy it and enjoy. My thought is that it will have pitiful low end power but will have drivability at higher speeds than a stock A.
The reason I ask about build style is that if done the "standard' way, swapping in a 239 later will be easy.
On the torque issue...Rod&Custom road tested a restored '32 B against a restored '32 V8, on the road and at the strip. Article has been discussed and probably posted here. The 221 V8 was generally faster, of course, but the B was indeed stronger at low end, and at the strip it was first for a little bit off the line and at each gear change surged ahead a bit, with the V8 pulling ahead on top end power in each gear and of course winning the race.
Ford posted minimum acceptable performance standards for acceleration, top speed, and mileage in the late 1930's Service Bulletins...I've posted on these several times. All performance figures for the 60 are pretty dismal. It belonged in a MUCH smaller car.
