Using a stock 4 barrel cast iron intake, how do you mount a 4412 to it? I have seen those adapters that just mount it over the center, but there is metal under there. Do you just mount it over the large two holes? I am trying to figure this out so I can try one of these out. Thanks.

There is a phenolic 1" slider type adapter that works very well there. It allows you to position the 4412 over the rear holes, or to position it centered over the intake if you mill out the 4 holes to connect them, leaving only the center divider. That intake works much better that way with a 2bbl, btw.

Let me know if you need to find one of those adapters. we have them as do many suppliers.

Kinetic Perf also makes a nice adapater, take a look at it on his website. It has 2 tapered sleeves in it. The theory being that the taper extends the venturi and puts more "pull" thru the carb. I've got 2 adapters from him, and I'm impressed.

I picked up an adapter from Summit for mine, it's a Mr Gasket brand (cheap) specifically for the Q-jet intake. It moves the carb back over the secondary holes. They also have a slider type like the one mentioned above, but it's about 60 bucks. I'm sure there are better ones out there than the one I got, but it's cheap (less than 20 bucks) and it seems to work fine for me.
