Will a Weber intake support high revs? Using a 250-260 cam in 427ci will make the peak very high...which to make it work properly will require heads that flow and an intake that will flow as well.

Aren't most of the Weber intakes made with tiny, short runners? When I think 6800-7000 rpm, I'm thinking Tunnel Wedge, Dove Spider, or a Victor FE intake....something with lots of plenum volume, long runners, etc.

I honestly think the cam manufacturers just don't know much about older, nostaligic setups. Do they ask any questions about the intake at all?
