Hi Guy's, I have a 4V manifold I purchsad for my 65 300ci. It does'nt fit, it's too long. I'm thinking it's for the same vintage 340ci or 350ci. I would supply the casting # to anyone interested. Since I have been doing a total restiforcation, I have a bunch of original parts for this 55k original car. 6 14" spinner hubcaps, engine parts etc. Low prices. Rick LiCastri Delray Beach Fl. :3gears:
