Edelbrock Performer RPM on a '69 Cuda 340 Hood clearance???
Jim
I tried the same method of measuring and I got 1 1/2 inches for the stock baseplate and 1 1/4 inches for the drop base. Mine is a MP replacement filter assembly, if that makes a difference. I was also using a K & N replacement air filter. The drop base as you can see has a flatter approach to the carb, so not sure what that does to air flow. They call it a 1 inch drop, but I measured closer to 7/8 inch.
