Can anyone identify this engine?

Re: Can anyone identify this engine?
looks like a TD with a custom P/C set also looks like it has a KK N/V assembly as well. with the way the cylinder looks, it may also may be schnurle ported. (Bandit)

One of the guys here (jsesere?) had a bunch of "blank" cylinders for sale, maybe that is made using one of them?

I'm not aware of any blank cylinders having a middle height wrench flat...
I could be wrong though.

Re: Can anyone identify this engine?
Bernie I have held in my hand two specialty FF engines made with the Cox cylinder blanks and they (IIRC) seemed to be all contiguous cylinder and color
I got the idea the owner machined in the exhaust ports and internal bypass and or boost flutes to some experimental secret spec
The one you show looks to be a two piece Cylinder
Do you have possession of this engine? Is it a two piece cylinder assy?
I have never seen one looking like you show

Re: Can anyone identify this engine?
One-piece cylinder and none of the Cox wrenches fit the "flats" to remove it.
Opposite the exhaust port one narrow groove and, to the left and right of such, one wide groove; but not exactly opposite each other. Someone put some thought into this.

Re: Can anyone identify this engine?
Schnurle porting would have two ports closer to the exhaust causing cross and back flow. It sounds like Schnurle porting of a sort. I would guess that the port opposite the exhaust is in fact a boost type with a taller cut than the other two.
https://en.wikipedia.org/wiki/Schnuerle_porting
The rounded ends on the exhaust suggest that the exhaust was cut with an end mill. If the end cuts are parallel to each other then it would suggest that the exhaust was cut in a conventional small mill. If the end cuts are directed to the center of the cylinder it would suggest that the port was cut on a multi-axis machine.
Now just because it is cut in a multi-axis manner does not mean modern construction as a dividing head such as for cutting gears could have been used to index the cut in process, but this is quite a bit of bother for a very small and probably entirely cosmetic feature.
All this really would say with how the exhaust was cut is how much tooling the maker had at his (or her) disposal. A high school shop from the 1980's would likely be adequately equipped. The quality of the work says that this was not a student project though. There are no false cuts visible. I would surmise it was made by a tool and die maker.
