Holley Street Avenger 670cfm to big for 318cui?

Thank you guys for your feedback!
I'll keep the 670cfm.


Now I have another question wich may is not worth an extra thread.
I have bought a "Weiand Intake Manifold 8022WND Stealth Aluminum".
Weiand 8022WND Weiand Stealthâ„¢ Intake - Chrysler Small Block V8

In the desciripion it is stated to fit for 318 - late style.
What does that mean? Will it fit my 1969? Or do I need another intake manifold?
The "early style" 318 was the poly. Their choice of words is poor. They should have said that it fits all "LA" engines. They mentioned the 340 & 360, which were both "LA". LA simply means "lightweight A".
