Default 4 cyl. Flat head, who made it?

We need some help trying to figure out who the manufacturer of this motor is. It is a 4 cylinder flat head motor. The tag on the side has been scrapped off, at some point in its life. Only thing we can make out on the tag is that it was made in Michigan, Y400 and 122 are stampped on it. After joining this group and looking through your posts, I found that someone had a motor that looked close to ours and that was a Continental. ANY help at all would be greatly appreciated. ANY ideas on how to locate parts would also be great. We need at least 3 valves as one is missing and the others are rusty. Motor spins freely and the magneto is in great working condition as well. Thank you so very much for your time!

Hello

Please post more pictures showing different views.

It looks like a marine engine from the pictures you have posted.

From the looks of the tag and with the Y code. I would say it is a Continental engine. They are the only ones I know that used the Y code. If I remember correctly the tag should read Continental Motors Corporation.

Give this company a call. They have helped me find engine parts when no one else could. P A Ross 1-800-229-1546.

That Y Continental block was made in several different displacements. In fact I have most of a Y block with internal parts that weill be scraped shortly. Do you have a Carquest part store near by? I also checked my NAPA book and there are 2 styles of both the intake & exhaust valves. Send me an e-mail. I have several sources for Continental parts.

As Billy and John have said, Cont produced a 4cyl Y-series, all 31/2 stroke; bores were 21/2 for the 69 cid, 27/8 for the 91 cid, and 33/16 for the 112 cid. All three were produced in truck, ag/ind'l and power unit versions; John can advise the differences (John: if you do, I promise I'll write it down and not lose it again!).
Some Cont engine lists in parts catalogs list a Y400, but it's apparently a misprint as Y-400-3 more numbers are parts numbers for at least some, maybe all, the Cont 4 cyl Y-series (there was also a Cont Y2, apparently a 2cyl industrial).
Buda had Y-series 4cyl's, all apparently over 4" bores; LeRoi's Y's seem to be all 2 cyl's; Lycoming had a Y 4cyl of 33/8 bore in the late teens/early 20's to ??, and Wauk built some Y's, apparently all 33/4 or 4" bores.
