If that's the stock iron 63-65 340 horse 409 intake,no wonder. just look at the #6 intake port at the flange. The whole W motor engine family had the most horrible intakes ever cast up. If they knew then what we know now!! That's the main reason that engine didn't breathe as well as it should have. Your dyno results showed a nice flat long power curve, making that engine way more useful. Amazing what a little technology does!!
