Hi guys-hope everybody's having a good day. I was fortunate off to get a ton of help from Forest and Keith today getting the "turbo" clutch issue sorted out. I can't say enough about how helpful they were and gracious with their time.

One of the things that I suspected, but it appears we now have proof of, is that this engine was built up from the original 2.0 GC case spec.

Can anyone identify these heads or help make a guess as to displaceme

The cylinders don't look like cast iron. Chances are they aren't a stock diameter, in that case. Likely between 96mm and 105mm. (Note that each statement in that chain is more and more speculative.)

"Button it up and drive it" sounds like the best advice. (IMG:style_emoticons/default/smile.gif)

Interesting looking cylinders, definitely not cast iron.

Those are aircraft cylinders, likely modified Lycoming or Continental.

Even the head casting looks odd, take the tins off and lets see.....

There is a test that is used by race organizations to "pump" a motor and discern displacement.

I believe it takes some equipment
I don't know how, nor whom can do it

but google it...
there is a test
you can likely pay a race shop to test it for you and give you some accurate informed guess....

leak down can throw the test results off, so run a leak down test first and then have the motor pumped.
