410, perhaps you mean the idle seloniod? An electrical thing on the side of the intake just under the center carb?
EL5, I certainly plan to have the intake fully ported. Some runners slightly dip downwards. I do not know how well it will port out and flow, but is has to be a nice advantage when done.
The Mod man intake above is an interesting idea. How would it fit to the '70 AAR hood?
