go to
www.racerwalsh.com, they have alot of special 4 cylinder stuff for carbureted 2.3L engines (alot of their business comes from circle track racers, apparently). I have a 1998 catalog and they have anything you can imagine for 4 cylinders (they have a manifold you can bolt webers to, and one that's a 4BBL manifold). It costs $3 and is well worth every penny.
