Call it what you want. He's installing a ede carb onto a ede performer.
No adapter plate is necessary. It is a direct bolt on with the correct gasket or gasket/spacer combo. Again no adapter plate needed.
No. He's installing a SQUARE BORE carburetor on a SPREAD BORE manifold. He certainly does need an adapter plate. Those spread bore bulges will forever leak unless he uses the plate mentioned. Been there done that. Been doin this stuff thirty years and 65Val is right on the money.
