Why the ZL2 flange needed the flat spot on Chevelles. On A/C cars, the vacuum tank would contact the Camaro flange.

Warren's post cleared something up. The May '70 Hot Rod has a LS-6 Chevelle test. The engine bay photo clearly shows the flange is not the clipped version. I thought they must have continued the Camaro part but looks to be the second design. Possible only A/C cars got the clipped version.

Sorry, the photo won't scan.
