273 4 barrel intake 64

Understood. Is there anyone who still manufacturers a manifold that can be modified? If so do you know the part #? Been looking for a D4B for a few weeks now. Thanks. I have learned so much on this site.

By the way, Welcome to FABO. Love your 64. I was looking for one when I found my 66 15 years ago.
Thank you! Worked on it all summer to get it on the road. My wife and 3 daughters love that car, me as well. Its my daily driver. I sincerely appreciate all the help!
