Default IO-360 A1A mount type?

Dyna II? I can't remember, and don't have the books yet for the motor.

Ryan,
My recollection is that engines used in single engine applications use the Dynafocal I [30 degrees] mount. Dynafocal II [18 degrees] is only used on twins. I know that the IO-360-A1A is used in single engine applications.
I just checked SSP 108, but got no clear info there. However, on page 36 [38th page on PDF versions], it shows that this engine is used in the Mooney M20-E & F. These are single engine applications.
I looked in FAA TCDS 1E10 R22 but did not see the mount style listed [am I blind?]
It seems odd to me that such a popular engine would not be Dynafocal I.
Charlie

O360 A1A is a Dynafocal I. Dynafocal I mounts intersect at about the starter pad.
Dynafocal II mounts intersect at about 3 inches in front of the flywheel.

It's in your builders manual.............. Plus, you can trust the man that makes the mounts.
