I have the same BX4 main body with down leg boosters on my pump gas 434 small block and have wondered if annulars would be better for my street/strip use.
My carb started as a Bigs 950HP, if I can come up with a four corner idle 1 3/4" base plate I'm thinking about building the 950 to test at the strip against the BX4.
I’m sure Summit will happily take your cc number and send you something suitable.
