With the bosses already in place it looks like you could P port that
Copper state rotary and just move the carburetors over.

I increased the taper on my needle valve and flowed 18.32 GPH at 3 PSI
and 13.48 GPH at 2 PSI. My needle valve is 7/16th Dia and tapers .020"
over 1 3/8 inches.
I don't like the idea of a mechanical fuel pressure gage in the cocpit
(ignoring the 29 gal fuel tank) so I might go with a flow meter for
leaning control. Karibian


I think you might need a positive displacement mechanical pump to make that system work well.

I assume you will brace those AL fuel lines?  they look like they could
easily fatigue crack.
