My 69 Firebird 350 has an Edelbrock Performer RPM intake manifold that the previous owner put on. Everything I have read tells me that this intake is designed to work at higher RPM's and that the Edelbrock Performer would have been a better option. Fortunately he did not get rid of the factory cast iron intake so I still have it. Is the only advantage of the Performer weight ? Which intake should I run with ?
