Edelbrock LD340 Intake Manifold Usable Max RPM?

Ask em what the .050 intake duration is. I’m betting you won’t get an answer. Maybe @GTX JOHN can chime in.

Duration is on Intake 260+. That is as specific as
I want to be. Exhaust is well over that.

The engine on our 340s will run 7500 thro
the lights.
