My early Los Angeles Road Runner had an aluminum six bbl intake



My Los Angeles 440+6 Roadrunner also has an aluminum manifold, with correct cast in part number style. Scheduled Production date Dec. 9, 1969. I've owned it since May 1975.

My scheduled production date was Dec. 8th. 1969



Engine assembly dates might be the best way to determine the time frame of '70 aluminum intake cars.
My Cuda SPD is Oct 12, motor is Oct 7.
Over the years I've heard there was a supply shortage of the iron intakes and left over '69s were used. Anyone know the real reason?
