Hercules OOC fit my 20c?

Howdy all, just noticed on ebay is a rebuilt hercules ooc engine

listing# 270513377424
title- Cletrac and Hercules OOC rebuilt engine

 I guess my question is will this fit a 1935-36 20c?

the listing says (& I quote)  "The following are casting numbers: Block-222010 E  11 94, Timing cover- 23339-D, and the head is stamped 22748."

Everything looks the same.

  Sure would be easier than rebuilding one!

From what I see, the Hercules OOC engine is what came in the 20C originally.  Obviously from the eBay listing, it has a Cletrac bellhousing mounting plate on it.  Why would it not fit?  

I think the other considerations for you are what you have that bolts onto that engine & what is missing?  Assuming the rebuild was done well, you still have a long way to go before it is all back together and running.  But you have a point about it being easier than rebuilding, and if the price holds, looks like it could be a lot cheaper too.  

One of the things I noticed in the photos - the output fitting on the engine that affixes to the flywheel has only 4 bolts - why not the full 6?

The flywheel usually mounts with 4 bolts and two dowell pins.  The dowell pins are very important, do not leave them out. They  position the flywheel exactly where it should be and are much tighter fitting than the bolts to resist vibration.

Thanks for sharing the information on the dowell pins, Robert.  I continue to learn from more experienced people on this site. My experience is limited to my AG-6 -- the F6-226 engine had 6 bolts to mount the flywheel.
