I have an Offenhauser flathead 4 bbl manifold which I am not using. It was on my 50 flathead for the initial fire up of the engine but has not been run on the street at all. It is almost new. It had a small crack in the oil fill tube boss which has been repaired properly and then bead blasted. These are going for about $375 on Speedway. Not using it would like to get $200 for it. Shipping is on the buyer.
