depends eh!?
I believe this is what I have now, an A3A....converted to straight riser intake sump...making it an A3B.
......do you plan to use a C/s prop? I like that it can run low octane fuel.

Sump
So if I read the chart correctly it will fit a 9A without changing the sump.
It is a plus that it will take a constant speed prop.
At 7:1 I would feed it Mogas !

need some experts to respond
as i understand it the curved riser tubes get in the way of the mount; the straight has them more forward...but don't quote me on the semantics.
Get an engine guy to verify.
also you want to know if the plug is in the (hollow) crank before you hang a C/S prop on it, and can't get oil to it!
ditto the expert required.

For an "A" model RV, the straight riser sump is the one you need.
I already replied to the other thread you started HERE
