Yes, the front plenum wall had to be cut out; not my car - belongs to Al Maynard.

Here is a photo of a 67 and a 68 cowl plenum air cleaner base. The 68 has the indentation for AIR pump clearance.
Also a photo showing a typical firwall cutout for the cowl plenum air cleaner.

According to Jerry MacNeish's 1967-1968 Camaro z/28 Fact Book the cowl plenum option was not installed at the factory. Instead they were shipped in the trunk with cutting and installation instuctions for the installer (most often the selling dealer). I'm certain all dealers didn't follow the provided instuctions identically. So even though the photo above shows an original cut out, it more than likely will be different than other original cut outs.
