Hi Paul,
You where right the Revmaster is an Edelbrock carb. I can get these
for $221.00 US each. I am waiting to get a price for the postage of
these units. Its very simple to modify the float bowl. in the
modification I will make the base hold both carbs. By making the left
and right you get a great installation and only have one leaning
valve.

It would be too small for the rotary but maybe all right for the
six cylinder 110 HP Jabiru if you used two.
Max rating on these is about 50 HP each.

The cross sectional area is what counts. They are about 40 mm which is
1250 square mm.

A Le Mans engine runner would be about 1.875" or 48 mm in diameter.
The area would be 1800 square mm or about 50% more area and HP each carb.
