RE: Just adding to the chorus of snorts here.

Those are the good carbs. I've heard that the trick 2x4 arrangement is two 450 cfm carbs. 900 cfm is plenty for a street or street/strip car.

Your carbs were stock on the 67 Shelby's. They're worth as much as new carbs, so you can sell them and buy 450's if that's what you want to do. You can sell them on ebay for $300-$500 each depending on their condition. If you don't want to fool with ebay, send me an e-mail, and I may buy them if you don't want them.

I'm also pulling around 8" at idle. The secondaries definitely open, but not at idle. The vacuum is low at idle, but that's because of the cam overlap. Once you rev up to 3,000 or 4,000, the secondaries will definitely open. They actually provide too much airflow, but you can tune the vac secondary springs to make them open earlier or later.
This thread, so far...
