The 36X was not sold as a combat special. The combat special was a different engine. I have several of each. There were also a couple different Fox combat specials. Side exhaust and rear exhaust.

Sure you can use a muffler on a sub induction engine but as the incoming charge is diluted with exhaust power will be way down so what's the point? The super Tigre G21/35 and G21/29's had sub induction porting too. At least the early ones did. Same problem. Why use an engine way down on power when you can use a muffled modern engine that will produce more power with it's muffler.

Sort of like removing two spark plug wires on a V8. It will run but power will be way down.

If you shim the cylinder so it sits higher so the bottom of the piston is not exposed you will lower the compression.
Power won't be down near as much as you seem to think. Subinduction occures near top dead center when most of the induction through the carb is done. Also the exhaust from the prior cycle has been disipated in the muffler So there is not that much back pressure left. With a very simple muffler on a G21 ST 35 combat, the power was still above most sport .35 engines.
