Technical Help identify flathead V8 (no block numbers)

Recently took the flathead out of my '38 Fordor Deluxe to use in a '28 roadster build. Outside of the casting numbers in the heads, I have not been able to find other numbers to tell me about this engine. Heads show 81T which would be a 221 but the T distinguished it as "truck," right?

A few photos and any help would be appreciated. Water pumps are stuck, but I'm hoping to salvage this. Could be a waste of time too. Open to info!

The heads have a 1938 part number on them. Block is probably a late 38 to 40-ish, but it doesn't have a lower fan mount on the crank so it wasn't used in a Deluxe 39 or a 40.

See if there is a bulge in the sides of the pan rails for freeze plugs. That would confirm those years.

 

Thanks!
I can confirm it has the bulges. I read that earlier and had confirmed it last night while trying to see other numbers. So you're stating it's a late 38 - 40 221?

 

Yes. The oil filter is a later add on. The transmission will have serial numbers up top so you can search what the case originally came in, but it may not be the same car.

 

Thanks, I appreciate the info. Bummed the water pumps are froze (my fault) but might be worth inspecting to see if I can make it run.

 

Give each water pump a short rap right on the nose, it might loosen it. But, if they are old they'll probably still leak. Kits aren't expensive, and are easy to install. Or, the new pumps with the sealed bearings are not expensive either.

 

Good idea. I know she'll roll over so that's at least in my favor. haha. The rest is just details at this point. I'll finish cleaning the years of grime off. She's well preserved I'll say that.

 

Looks like numbers on the flat spot of the bellhousing.
