amazing shine! i would just build another garage for it.cars like that are once in a lifetime for most people.

did you clear coat the car?dam shiny for being originall 66 paint.but still would not have let it go.that original of a car is a rare find today!

Still looking

Don’t even look at the A/F until you have some heat in motor/ exhaust. Idling cold with a big cam will give confusing numbers. ( and a cam with a lot of overlap combined with a low idle can give skewed numbers even when warm)

     But actually at anything less than the engine speed (R.P.M.'s & throttle angle/load) that provide for at least some form of reasonable directional stability, in both the induction and the exhaust pumping, one will be provided with questionable numbers from O2 sensors.   

     Obviously a major problem with this style of intake is going to be fuel control, particularly distribution at low engine revolutions, compounded when the induction doesn't present an adequate sum of heat to aid in the vaporization of the fuel; and the staged carburetor opening just makes for even greater challenges under these conditions.   

     Though I do understand the intention of "streetability", and yeah I am aware of how Ford Motor Co. dun it, but particularly with bigger camshafts, in all honesty both carburetors really need to mimic/mirror one another, which one will find will better the situation.

I would put an electric choke on the front carb. Let it warm up that way. Set the kickdowns for 1600-1800 for high and 1200 for low.

Drive at least two miles before you get to tuning/worrying about cruise A/F.
