consider a surge tank instead.
not a hemi, but efi in a 65 coronet vert.
I just got a new tank and had it coated and decided to put in efi.
Didn't want to cut and weld the brand new tank. or use the areomotive kit as I wanted to keep my gauge as well.

I don't recommend the surge tank I got, as I found it was hard to seal up because it was round.
works fine, just a pain to set up.

So a member on here sells one, also fi tech has the commander setup as well.
