The 1st picture is of an Indy dry sump block like I posted up above. They had an internal dry sump setup.

Quote from Doug

"Now while in discussion with Vermersch (and I discussed this with you as well if you remember) I asked about the "small port" A331 I had. The outside of it was from the same mold as the "regular A331's) but the port exists were the size of production 302 iron heads"

Maybe the small port intake was designed to be used with a set of heads like the one in this picture with the Windsor style port. I have a set of them on my small block in my Mustang with a 2x4 TA intake.
Since we were discussing main caps I thought I would throw in a picture of an unmachined one also.

Yes they look like Windsor size ports but the only point would be to make a 9.2 Windsor/Cleveland hybrid. What's the point.

I think it more practical for someone who wanted to port match B302 Motorsport heads on a Cleveland? Actually I traded it away and that was the intention of the recipient as I was told.

     Not really , you would have to see the head. It really improved the bottom end torque , something Boss owners complained about "in the day".

Well I don't remember them doing any Cleveland stuff but those guys over at Valley Head Service were epoxying up B2 intake ports way back when the B2 was new to T/A., so other then casting up B2 Heads with intake ports to match 302W's intake ports, I would think that my small port manifold was made with thoughts of cans and cans of Devcon Plastic Aluminum getting put to use? At least experimentlly to try on the flow bench?

I will point out that my intake did come from So Cal. Maybe someone just grabbed it out of the scrap pile? It only cost me $100.

The C8FE block continued to the D1ZE block which I believe was its final Ford produced iteration.
Any comments on the C8FE's further engineering changes which resulted in the D1ZE?
Did the D1ZE have a thicker deck?

You needed to check but a lot of the D1 blocks could be bored .125 over.

These pictures show my BOSS 302 Dry Deck block

The first picture shows that originally the block was an SK45693 block, However it was later changed to the XE149282 block.
These designations on the pad on the front of the engine would give you the details of what the block was IF you had the SK log book

The second picture is the C8FE part number and date code November 29, 1967 Dated BOSS 302 block? No it probably sat unmachined in a pool of blocks waiting for a decision to be made on it's eventual configuration.

The third picture is an overall deck view.

John, it's hard to tell on my phone but isn't the last picture one of a Tunnelport block?

No, there is not a passage for head oiling to the deck, There is material there to drill the hole but no hole.

   +1 Casting is the same so the passage is there but not drilled.

Are you saying that all the C8FE block castings are the same?

   Visually , YES , except for machining variations for the specific applications.

Refresh my memory please? Didn't I get slammed for suggesting that?

   I don't know. The blocks ( externally) look the same. There was "some" experimentation done on the internal core patterns to produce "square bores". Those had hand scratched SK numbers in the bell housing area. Some were machined for the internal dry sump Roy showed and others were "dry deck" for Tunnel Port heads or Boss 302 heads and others for regular head gaskets,

So isn't the bare casting, in 1968 terms, a racing block casting?
