As we've previously discussed boring our y blocks to 4" and knowing they split the deck between cylinders. I wonder if the sleeves were all fabricated to a deck plate and pressed in as one.
Therefore the plate would strengthen the deck being re secured by the head bolts/heads. Perhaps .250" plate.
Which would give more stroke length.
What's your thoughts?

CK, I don't think you were with us when Verne Schumann was setting out to produce an updated, enlarged Y-block. You may wish to dig-into some of the earlier information on this proposed venture.
Below, I've copied a piece of a posting Ted Eaton made about a year ago below that should help you get into this... ________________________
For the proposed iron 4.125” bore capable cylinder wall blocks for the Y, Verne Schumann needs a commitment for 35 or so to make it financially feasible. He’s having difficulty getting that number of commitments but part of the problem has been in getting the word out to the masses. This is something that needs to hit the mainstream publications rather than just a few internet forum boards. Once Verne has enough people interested in blocks, then a finished block could be ready in as little as nine months..If anyone is interested in one of the new iron Y blocks, just give Verne a call and get your name on the list. Here’s the link to the past thread giving some of the more pertinent details. http://forums.y-blocksforever.com/Topic76753.aspx

I would like to know based on vernes proposed 35 1st run, the approxamation of the cost of the block, so there may be more interest then, to me its such an unknown factor holding back my interest.

I copied this from another of Ted's inputs to the thread referenced, AussieBill...
Ted (2/4/2013)
I found this full page info sheet detailing the new Schumann block casting in Y-Block Magazine issue #109. Suggested selling price for the block is $3975. Click on the link below the picture for a larger image that’s easier to read giving more detail on the block.

My recollection is that Verne's price was for a fully machined block, too!

No Shortcuts,
Thanks for vernes specification sheet re proposed new block, looks good ! i had thought there was talk of moving cam tunnel higher but this shows will be standard.

Yet if the sleeves were screwed into the plate, or if a 1/4" plate was introduced which the sleeves rested in. Do you think it would hold the forces?

As John M pointed out to me, moving the cam position causes other problems, the distributor has to be moved which then causes problems driving the oil pump.

CK, Ted Eaton, Tim McMaster, and John Mummert (perhaps others) have done everything possible to enlarge an existing Ford y-block to obtain maximum cubic inch displacement. Both Tim and Ted have pursued the sleeving of all eight cylinders. My recollection is that Ted's was to accomplish a 4 inch bore.
An internally redesigned engine block casting, like that proposed by Verne Schumann, is what is called for.
In case you missed it, on 8-16-14 one of our members posted this article regarding John Mummert's latest exploits working within the existing y-block casting form.

A deck plate will also require that other issues be resolved, like spacers for the intake or a custom intake, header clearance , hood clearance, It is an expensive proposition, possibly expensive enough that if you are serious, you need to call Verne about that block.

...and block might crack somewhere because every headbolt will stretch.
But plate machined in to block around cylinder tops might work. I have heard some rumours that some turbo-Nissan guys do that.

As for the manifold, a pair of spacer plates could assist.
And regarding the cam, well I'm not looking towards a larger stroke than 3.5".
I have heard of sleeves being fitted and after a hard day at it the sleeves began to move. This another reason I thought adding the plate, just like a turbo plate yet one that is attached to the sleeves, screwed in or welded before pressing in. So the plate sits on top of the standard deck.
I remember talking to Lyndsey y bloke about bill saintclair and that he fabricated a block from steel plates. This has been another way about it I have considered. Yet fabbing from aluminium plates.

hi, massey harris did that with a tractor motor. they cut the block out at the top and cut the cleeves out at the bottom. they used a 1/4" steel plate and furnace brazed the new sleeves in at the top. they sealed the plate when they set it down in the recess in the block at the top and they used O-rings at the bottom of the sleeves like a diesel. don't know if it would work with a high rpm motor. it still would be expensive unless you had a mill and a boreing bar.
