I JUST saw these.  Advertised on eBay as 312s.  Located in Walnut Creek, CA.  Seller indicates that they came out of a two engine boat, but the transmissions are different.  I don't know y-block marine applications.  My understanding is that IF from a two engine boat, one engine rotates the prop in the opposite direction of the other.  I've been told that the marine reverse drive y-block takes a different camshaft.  -I don't know this to be fact.

The eBay seller lists the 2 engines w/ transmissions as a package.  The seller's opening bid is $1,500.  The auction ends in ~17 hours with no bids made presently.  Hard to tell what shape any engine is in from outside pictures.  Seller indicates that engines have not run in years and that aluminum parts have corroded from exposure to the air.

Curious that while both engines are listed as '57 vintage ECZ 6015-C blocks, the casting parting lines on the cylinder heads indicate that one set of heads are post '57.  My thought is that the one set of cylinder heads' outside casting parting lines suggest them being 113 heads.  113s were Ford's replacement heads for y-blocks after ECZ-Gs went out of production circa 1958.

While both engine and transmission assemblies are said to be complete, I doubt that anyone will purchase them as advertised for $1,500 or anything approaching the 'Buy-It-Now' eBay seller's price.  Anyone purchasing these from outside the CA area would likely pay a fortune to ship these any distance.

The purchase price may be negotiable for these after the auction has ended.  Consider communicating with the seller through eBay before the auction ends IF you're interested.

This is not my eBay listing or my engines.  Hope this helps a Forum member.
