Dale Powell designed that carb to work with the Ventura on the carb.

Lots of time and testing went in to that original Ventura.

If any thing the add on ventura will hurt the performance on that "particular" carb.
 
It has bin many years since Speedmaster has made those carbs.

Very narrow profit margin in producing them.

CNC time is valuable and the rest of there line takes that all up.

Dale has made some jigs and started to make some carbs on his own.

But life has a habit of get in the way as with all of us.
