I am looking for a Wieand 7503 Intake manifold for a A318 Poly motor, also finned aluminum valve covers. Or a stock cast 4 cast iron 4bbl would work as well
I found 2 poly 4 barrel intakes years ago at a junkyard. They were on Chrysler Marine 210 Furys. You might have luck searching at a boat/marine scrapyard.
