Thanks. There is a centering/sealing ring that I machined to line them up perfectly

How much would charge to make another lower like yours???

I had a 89 23 Daytona and at 4000 ft and 502 carburetor ran 60. built a 502 with M3 Procharger it ran 90 at 5500 ft. 8 lbs boost. never ran it at the 4000 ft.

If I were to do another idea use a imco shorty and adapt it. It's just not economical to shorten a bravo. I did it because I had the pieces and the tooling.
