Aluminum 4 BBL manifold for a 64 question.

I found a D4b on ebay for the 273 in my 65 Barracuda. Just got it installed a few months ago. It went in fine. Seems to work good. Haven't had it on the strip yet to see if performs better than the factory single plane four barrel that I used to run.

That being said, it is my understanding that it doesn't take a whole lot of grinding to make a '66-up manifold work on the 64-65 heads.
