Airframes Alaska also makes a zero thrustline mount that is lowered to keep the original top cowling line. Experimental only.
If this were approved, and was a stock installation, would it all otherwise fit without any modification?
Don't know about you, but I like excited! But at my age.....It should. It was designed to put the flywheel/prop flange in the same location as factory but with a zero degree angle. Basically there is about a 3" rise at the front of the engine after installing zero thrustline spacers and that is the amount the engine is dropped so that it's still zero thrustline but your cowling doesn't look overly excited.
I have Javrons lowered mount on my Javron cub with an 0-320E engine and have dual impulse Bendix mags. No interference problems on mine.
