grumpin Posted April 14, 2019 Share Posted April 14, 2019 https://klamath.craigslist.org/pts/d/medford-exhaust-manifold/6845182555.html I don't know if they are correct or not. Thought someone may be looking. My 1978 Ford Van with the 351W would crack one manifold on the right side I believe. They all did it, my JY searching ended getting the best one I could find for $10. Had a friend weld it, he did a good job. Link to comment Share on other sites More sharing options...
Gary Lewis Posted April 14, 2019 Share Posted April 14, 2019 Hard to tell w/o a part number. I'll see if I can remember to pull Dad's out and take a pic of them. Link to comment Share on other sites More sharing options...

I can't remember if the 77-79 trucks had the same exhaust manifolds as the 80-82 trucks, but those are definitely NOT for a bullnose 351M/400. More than likely these are car manifolds, or 77-79 truck manifolds. driver side might be the same between cars and trucks, however the 80-82 trucks had a unique to them passenger side manifold.

From 1977 to 1982 the M-block truck right hand manifold is D7TZ 9430-A, and left hand is D5AZ 9431-A. Link to comment Share on other sites More sharing options...

Edited my previous post after realizing I had the sides and years mixed up. It's been some time since I've spent time working with boat anchors.
