71 440 exhaust manifolds
« on: August 25, 2015 - 07:29:52 PM »
Is any one making new manifolds for 71 E-body 440? Checked year one and found a listing for 68/69 B- bodys but no E. My driver side manifold is warped and causes the stud near the fire wall to break. Took the head to a repair shop and he took one look at the head and knew it was broken stud at the end. Said that is where they break and he has been doing this for 30 years but he didn't know why. Well I showed him the manifold and the way the holes line up, because it's warped and the weight of the pipe is on that end the stud fails. He also showed me a bunch of gen 3 hemi heads in for repair because of intake seats failing! He saw my srt and told me I am lucky it hasn't failed yet. Said the seats only had .001" interference and that new seats have .007"
