BUT MY WEDGE PLATE HAS THE SPREADBORE PATTERN ON BOTTOM. HOW CAN I AFFECTLY MOUNT THIS WEDGE PLATE TO A AFTERMARKET INTAKE AND NOT HAVE A VACUM LEAK. WAS GOING TO RUN A EDLEBROK BIG BLOCK RPM INTAKE.

my problem is this, bottom of wedge plate is q-jet and wanna put it on a standard aftermarket dual plane manifold

So can't you put one of these adapters on the intake first and then your wedge plate on top of it? What carb do you plan to run on top of your wedge plate.

run a holley, but dont have the room under engine cover to do that, there would be no room for flame arrestor, and that would mean , i would need to make room in the glove box for the tickets for no flame arrestor,lol

So will a holley bolt up to your wedge plate? Are you even going to have room for a taller intake like an RPM? I know the engine cover in them ski boats is right on top of the engine. You may have to use a different intake thats for a Q jet.
