My Holley doesnt do that and I dont run a spacer

How does your aircleaner fit now?

There are a lot of things that can affect it besides a spacer.  In my opinion, the multiple gasket, aluminum insulator bit was the mitigating factor here.  Too many rough surfaces for the air to start jumping over.  I could be totally wrong but that's the part that made me suggest a one piece spacer.

It hits the hood insulation pad a little more, but it works. You using a stock intake Chris? I will get the number off of mine tomorrow and we will compare. Its either run the spacer or get an aftermarket intake. So I chose the spacer because I want to keep it stock looking as possible.

Or you could get this other hood I have and shove something through it....

Its an Edelbrock CH4B which is the aluminim replacement for the cast iron Mopar piece......my air cleaner hits the molded pad I have.  The pad is so coarse that it is grinding down the pie tin......I actually bought a "show tin" for shows because it looks so bad
