4 barrel carb questions

Now for the kicker I'm tinking of doing this on my 62 Valiant wagon with the mechanical linkage throttle.
Thanks for any and all assistance.

Offenhauser made a linkage adapter kit to connect the stock slant 6 rod linkage to a 4 barrel mounted on their slant 4 barrel intake. Not sure if it's available anymore. I'll take some pictures of the one I have, which is NOT for sale.
