SB Intake Manifold

Check the last 3 numbers of the casting numbers on your heads, If they are 65 dated heads, the last 3 numbers are 315, the casting numbers are located under the rockers arms. I have a Edelbrock D4B 4bbl intake I would be willing to sell. It is in great shape and very clean. I paid $225 for it, I would be willing to sell it for the same price + shipping.
