In 66 Chrysler never had an aluminum intake for the poly motor. I am not even sure if the 4barrel cast intake and carburetor was available from the factory in 1966. The only aluminum 4 barrel intake available for the poly was aftermarket made by Weiand. I have one on my street car. The poly motor was the "A" block. The later 318 block was the "LA". The poly was phased out of U. S. passenger car production at the end of the 1966 model year. Truck used them in 1968, for how long in 68 I don't know. I heard some Canadian passenger cars had them in 68 but were all done by 1969.
