Edelbrock LD340 Intake Manifold Usable Max RPM?

Thanks for more empirical feedback.

Do you happen to have the cam profile you ran?
I don't know if this is any help, as it t was an old Cam Dynamics. I believe Crane now has the masters from Cam Dynamics, but I'm guessing as old as this is (1980s) there are much better profiles available now. if your rules package is lift-limited I'd talk directly to one of the cam companies, as they can make up for lack of lift with longer duration, like they do with stocker cams.
