Edelbrock Performer Vortec VS. Performer Vortec RPM Air Gap

Performer RPM Air Gap on left, Performer on right.

i had to get the intake machined a little so that the air flow didn't get disrupted.  You can see in the first picture below that the "ledges" on the intake stuck out into the area where the throttle body sits on top of.  The butterflies didn't hit, but they came really close.  But, this was obviously a bad thing as far as air goes, so I had the ledges smoothed out.

Here are some pics of the installation.  I didn't get it all finished yet, but it's almost there.
