I don't know what kind of motor mounts are in my car, but I do have an Edelbrock Performer intake with Edelbrock Performer carb and the 14" AC Delco air cleaner. This air cleaner (and yours) is a drop base design. However, the drop base design is designed for a Holley carb, and a spacer is required for the Edelbrock/Carter carb. I have a 3/4" spacer on mine. I can tell you that this will not fit under a base flat hood. I have a stock height cowl induction hood, and the wingnut pokes through the hole in the hood...I can see it and the top of the air cleaner housing from the driver's seat. I also have a regular Performer intake, not the Performer RPM which is a little taller. No way this combot will fit under the stock hood. Prior to the AC Delco/GMPP air cleaner, I had a K&N chrome air cleaner housing with the identical setup. The lid is a little flatter, and it did fit under a flat hood...I actually had the original flat hood on the car at that time....so the K&N air cleaner might be an option for you.
The pics of my car in the signature are old, so if you look at the engine pic, the K&N filter is on the engine...you can see how the lid is pretty flat.
