I have a nice pair of 340 exhaust manifolds off a 340. Part numbers are 3614368 with a casting date of 11.28.72 on the drivers side and 3418623 with a casting date of 11.20.72 on the passenger side. Pretty interesting they were cast 8 days apart. Both are in nice shape and the heat flappers moves freely-the extension spring is still in place! Only issue I can see is part of the very back ear is broken off on the drivers side. Should be a pretty easy fix. Asking $300 plus the ride or local pickup at 49425 zip code. I used PirateShip so that will save a few bucks on shipping. Pm me if interested. Thanks for looking!!
