    Stumbled across this on my morning MTB ride. Might be common, might be rare? Couldn't find anything that matched with a quick google search so... any help is appreciated.

    It's pretty neat looking – if nothing else I can use it as a base for a table or something in the shop.

    I thought it might be an Oldsmobile like in my 46 but it wasn't. I did some searching and looks to be a 230 Dodge? Fuel and oil pump on passenger side, distributor and oil filler on driver's side. Is there a casting pad with any numbers to go by?
     
  3. I believe Mopar also.

  4. I think mopar flat sixes are a 5 main block. I will check the old Motors Manual tonight and try to remember to get back here. What are the basic dimensions on this thing? height? width? length?

    Bore diameter might help narrow the choices down too.
     
  6. Studebaker. MoPar sixes have 5 mains.

  8. I think, Mopar.

    My Plymouth Service Manual says there are 4 main bearings in the flathead 6.

    I have seen plenty of four main straight sixes. And lots of seven main straight sixes. But i have never seen a five main straight six. Don't mean there aren,t any. Just means I have never seen one and I don't expect to. The five main inline six seems like a curious arraignment. Can some one explain how the main bearings are situated in such a motor? 4 or 7 seem to work out evenly. I have a couple of 5 main Dodge Bros. four cylinder engines. But they are not MoPar engines.

    I see the oil filler hole but not the distributor hole so I don't think it's a Chryco engine.

    With no main caps, it doesn't really matter ...

    Fuel and oil pump on passenger side, distributor and oil filler on driver's side. [​IMG]

    1/2 way down the block, the dizzy comes out at 45 degrees. Engine number is stamped on pad above freeze plug at front of block on driver's side. Also I note dipstick boss and oil filter takeoff. Post war Flat Heads generally have the build date cast in just below the distributor. I could be wrong but Googled away and this was what I found. Lots of other possibilities?

    sure looks like a Stude Champ engine.

    Doesn't look a bit like my Dodge or Plymouth blocks. (Only 4 mains guys.)
    The screw holes below the tappet galley don't look like Mopar to me.
    The driver's side pan rail is all wrong, the headbolt pattern is wrong. The manifold bolt pattern is wrong. Unless it's much older than mine this engine doesn't say Mopar at all.

    Yeah, see the Stude had a coolant passage at each cylinder right where Mopar has a headbolt.

    Hmmm...my serial number indicates a 1953 Dodge engine, but the block says: 50 6-28 cast below the distributor. I don't think it's a date.

    another look at the two...maybe the mystery motor and the Stude could be more identical, but I don't know how.

  20. Yup, you're right...only 4 mains in a Dodge/Plymouth six. Must have been a Freudian slip; I've been reading about Model A 5 bearing cams :)

    I stand beside my contention that it's not a MoPar product; it's a Studebaker.
