This is the back of a 223 I-block engine. Note the 4 engine to bellhousing boltholes and the two alignment pins

This is a "starter plate for a 215 I-block 6 for a Ford-O-matic. It has same bolt pattern as the 223. The starter plate for an engine used with manual transmission is cut-off below the red line. The manual trans has its own separate stamped metal flywheel inspection plate on the bottom instead of this.

If you were going to make your own adaptor plate, it would be best to first know what the radius is from the crankshaft of the Y-block to the engine-bellhousing mounting bolts as a starting point. Knowing that the radius is 8 inches for the I-block, you can see that you will have two radii layed out on a sheet (the smaller radius being the I-block and the larger being the Y-block. Then you can lay out your bolt hole pattern.
How would the starter work though? You have a manual trans with a smaller flywheel than that used for the Y-block. Will it even be possible to mount the starter so that the starter Bendix touches the flywheel gearteeth ? need to closely look at cast iron ribbing and bumpouts at the back of the Y-block to make sure that a mounting bolt for the manual trans bellhousing doesn't hit the ribbing before driving the bolt home. All kinds of things to think about !

Dave,
Thanks for the pictures, I believe I have all info I need.
For what it’s worth Pat @ http://www.wilcap.com/webdoc8.html is a great guy to talk with, he just doesn’t any 223 dimensions but, was a great resource on pattern making and flywheel info.
Again thanks
Ps if I do pursue this I’ll be sure to post some pics

Thanks for everyone's help.
There is a practical reason this has never happened. Even though the 4 cylinder shares similar architecture with the "Y" block the starter on the tractor goes where the oil pump and filter are on the "Y" block no work around. I'm sure I'll have another hair brained idea before the end of the day.
Thanks again and have a good day
