Now you can fit your dual IDA carburetor kit under the deck when using our tall Big Beef manifolds. A perfect fit and beautiful finish to top off your IDA series carburetors. Polished inside and made right here in the good old USA from 6061 bar stock.

These stacks have the added feature of an auxiliary venturi securing ring, this is a must if your carburetors do not have the auxiliary venturi securing screw.
