Offenhauser equa-flow manifolds for the 1965 273 engine

Yes. Be patient. You are searching for something elusive. You will find one. Or look for 66 and newer 273/318 heads and then you have more intake choices. It all depends what you want out of your 273.

Thank you, I want to ad the D4B for my personal use and keep the heads original. I was lucky to get a nice rust free 65 Formula S from Nevada a couple years ago and don't want to molest the heads. I hear what your saying but trying to keep it as close to original for resale. Joe
