Topic: 21 Stud Flathead Identification


JerryG    -- 09-30-2010 @ 4:37 PM
  Hi Gang. I just rescued a 21 stud flathead from a '34 Ford being rodded. It is the '32-'36 style, with iron heads (40-6050 with what could be a "B" suffix, Ford script and a large raised "F" above the numbers). Have not pulled intake to see if this is a '32-'34 or '35-36 block. Has '35 flat top distrib, right front vent pan, and trans stamped maybe * I8I2T3265*. Can I tell if this is a commercial/truck engine, or a car block with iron heads? Does it matter? My new '33 thru '39 V8 Club books really helped so far. Thnx, Jerry G

  JerryG,
Distributor sounds like a 68 which is a '36 item. The iron heads, distributor and trans are all things that can be changed through the years. If there are no block off plates where '37 water pumps would mount you know it is '36 or earlier. If it is a inserted main it is '36. If it is poured mains, it is early '36 and back. If you have a '33 to '36 car that needs an engine you should be excited because you have it.

I believe there are minor/slight (in the eyes of the beholder) differences from '32 to early '36 engine blocks and there are experts that can give you some things to look for. It wouldn't hurt my feelings too much to have an LB in my '34 cabriolet!

Hope this helps,
Ken

  Thanks Ken. That's what I am thinking also. With a flat top distrib it is possible it may be the late '36 with the inserts. As luck would have it, I found a '35 Touring Sedan parked in front of muffler shop this morning on the way home from getting tacos!! It is original..and the engine compartment looks like it has never even been cleaned. It has cast iron heads also. The only thing clean and newer looking is the fuel pump. There is an older Early V8 Club sticker on the windshield. I am going to ask about the owner today to see where it its kept, so I will have a local original to work from..and maybe a new buddy!!

  You can eliminate the '32 by checking the drain petcocks on the block, near the front, between the exhaust manifolds and the pan. If the petcocks point straight down, the block is a '32. If they point slightly outward, toward the frame rails, the block is later. '32 blocks are rare.

  Also, if the number on the transmission is really 18-1,213,265 (punctuation added) the transmission is a late '34. Note that Ford sometimes used the capital "I" (eye) as both a hyphen and a "1" (one) when stamping serial numbers.

  The vent on the right front of the oil pan was first used in 1935. Randy

  Thanks Ken, Deluxe and RSS. I checked the pet cocks and they are angled. That's it for now. My hope is that this is a late '36 with inserts, etc...since I think I have seen that this is the best of that block series. I won't know that until later when I can take the stuff off and look inside. Jerry G

  Ole Bill, For your edification, tacos from roach coaches in the mornings is rebuilding America's infrastructure!

  Ole Bill, Ford38v8 is right. You aint lived til you have breakfast tacos in South Texas...just about anything you can think of in hot homemade flour tortillas (not the crisp corn-tortilla-sh*lled tacos you may be used to for lunch or supper). We slap hot flour tortillas around anything, even polish sausage, down here. Es Muy Bueno!!
