Have a 71 350-4 with 72 heads. The intake has casting # on back 1238647. I have compared this to the #'s listed for the Buick engines on atlantabuick.com website, and it doesn't match any of them. Anyone know what engine/year this intake came from? The full # is B-1238647-2, also shows B/7. I do know this engine was professionaly rebuilt about 6,000 miles ago, in about 1996, and the receipt says "recon heads".
