Another V8 Identification Thread (1940 Ford)

[WarbirdPhotog]

Hey everyone, so I've been reading all sorts of threads on how to identify V-8 engines, and I'm still coming up with a blank on the one in my 1940 Ford. After spending the better part of a half-hour hunting for any identification, I'm coming up empty.

Here's what I know:
- There are 24 studs on each head
- Water pumps are in the block
- Petcocks are a 45 degree angle
- There is NO 59 on the bell housing
- There are no stampings anywhere on the block that I could find
- The passenger side head has:

A
FORD
56
- The Driver's side head only has an A
- The rear of the block front plate has 22 on the mount arm on the driver's side, and 78-8505 with an 8- on top of that on the passenger side.

45 Degree drain plug (I think that's it correct?):

No 59 that I can see, even looking up behind the firewall:
