I have a 4500 1050 I have been using and it was suggested I could use an adapter to put the 4500 on the 4150 flange. This is on a BBC. Not sure if it is cost effective or what the end result would be for performance. There are some reports to suggest positive results. The manifold is a set up for an offset magneto. It had some machine work to it and for the offset. I want to know what some of you all thoughts would be. Thank you
