Yes, the Edelbrock Performer RPM puts the carb up 1.5 inches over stock.

The regular Edelbrock Pontiac Performer intake manifold is an copy of the aluminum factory RA IV and leaves the carb at the stock height. But the non-RPM manifold is not going to give you much of a performance gain on a stock or mildly modified engine - it is only going to shave some weight off the front of the car.

I went with the regular Performer because 1) I needed a new intake anyway for the 455 block I was putting together, 2) I liked the weight savings and 3) I planned to install an aftermarket Ram Air kit and needed the carb at stock height.
