Slant 6 4bbl Carb Selection

Sigh.
When will the BS stop???????
[1] 750 Edel secs will never open. Yes they will, they are a mech sec carbs. The secs go to WOT when the primaries go to WOT. The sec vel valves may not move, but there is a lot of air leakage around them that could lean the mixture.
[2] Prim are no bigger than a 350 Holley. Yes they are: Edel Pri 1 11/16", Holley 1 1/2"
