I've got a quick question. Will the new RPM II upper intake fit the performer lower intake? The current upper Edelbrock Performer intake I have has all the mounting tabs broken off of it, and I've been wanting to sorta upgrade for a while. I've looked for the old Performer RPM on summit to use, but they don't sell them anymore. So now I'm stuck with buying either the Performer or possibly the RPM II if it will work. Any ideas?
