Hey Fordbarners,
Any way to tell if this is a AA truck or car motor? possible year? the U joint setup looks like it may be out of a truck?
Thanks!!

Is there any number stamped on the driver's side of the block? an AA prefix will mean it's from a truck. An A means passenger car. The engine looks like it's post-mid-1929 if the e-brake is original.
 
The fan is one that was used on commercial vehicles, but that too could have been changed somewhere along the line. As Ray says, the AA prefix on the serial number is the "for sure" way of determining if it was originally installed in a truck. The transmission and bell housing don't really look like AA units though.
 
That is a 3 speed car transmission. The drive shaft has been altered either to install it in a stationary power unit, or a cut down home made tractor.

Interesting shift lever. That might suggest a home-made tractor, or some other farmer fixed rig.

I hate to disagree but the fan is the one introduced in 1933 (part number 46-8600) for the 4 cylinder. It became the replacement part for the Model A. The Model A commercial and passenger vehicles used the same two blade fan throughout production.

Truck and car motors were the same motor. The AA stamped on the motor only meant that the motor transmission assembly as shipped had a heavier truck clutch or 4 speed transmission.

Thanks for the responses, the engine is for sale locally, i havent seen it in person, just the pictures. And it doesnt say what it came out of. Pretty complete.

Not completely un-related: Did the AA trucks use the same steering-gear as the cars / pick-up ?

The main steering box should be the same, but the pitman arm as I recall was heavier on the late 30 AA I worked on. Neil Wilson would be the AA expert. I know the brake pedal for the AA is heavier.
 
the throttle linkage is mid 29 to sept 30
the brake light switch is 29
just get the engine number off the drivers side of the block
it will date it

I don't doubt that what you say is the gospel truth, but; back in the old days when I had my first Model A (a '31 AA 280A) which my Dad had owned previously (I think he bought it in 1949 or so), It had the original fan on it and it was a 4-blade riveted fan like the one in the picture above. Just sayin.

For any Model A it was unusual for there to be no changes in 18 years and I'm sure the odds doubled with AA trucks. Yes, it's a fact that the propeller fan went beyond 1931 on the four cylinder models but if you went to Ford for a new fan in later years you would receive the four blade fan.
 
You are correct Marco, it was 18 years old, but what makes me think that it was original was that the vehicle only had less than 10,000 miles on it when Dad bought it. It was an ambulance for a coal mine in northern NM, and sat idle most of the time. Dad bought it from the mine when they retired it. I wasn't there for the first 18 years of it's life, so I may be totally wrong in my statement.
