Older Edelbrock Manifolds

There's a tech article on the Early Valiant & Barracuda Club website that discusses the evolution of Mopar engines........ in that article, it says that the bolt angle on the 1965 273 was changed for the '66 and up.......

That's why I felt it was paramount to confirm that the D4B that I bought on the web was truly for a 1965 273. It did fit my '65 heads just fine, and I am inclined to surmise that the tech article is correct.

In fact, I saw a thread somewhere on this website from a lady who is having head/intake problems..... I think she put heads from a '67 (maybe) on her '65, and now her '65 intake manifold won't "fit".......

So if you're buying parts for a '65 273, beware.
