You must be turning some serious RPM's. The Stromberg BXOV's came in different venturi sizes, the largest was 1 7/32". Their size is molded into the carb in a small circle right next to the fuel inlet. If you are needing just a slight increase, check your venturi sizes. ??
In the old days McGurk recommended 2 or 3 of the 1 5/32" BXOV's. If you have the 1 5/32" just going to the 1 7/32" would give you a 'slight' increase. I would not recommend going with 5 carbs for a street driver as you really start to loose your vaccumn. But it's fun to play.
