C-4 Converter for Sale

I have for sale a ACC Boss Hog converter that fits a C-4. It has the 11 7/16" bolt pattern that fits the pan fill, large bell C-4. I had it sent off to set the stall at 5000 for a N/A 306. Has not been installed since the rework. Asking $400. The reason that I am not using it is cause I have the small bell, case fill C-4 that uses the 10.5 bolt pattern. Buddy R Hill 870-673-1106
