So after thinking about it, I might be going in a different direction and just doing single 4 barrel. I have a very good factory intake that has been bead blasted and the correct valley cover. I will post photos this weekend if anyone is interested. -Zach
I am pretty sure 1957. I thought I had all the paperwork at my house but it is with the intake at my storage unit. I will go there tomorrow and take all the pictures.
It is the aluminum dual 4 barrel intake from 1957 for the 312 Y block. It has been cleaned and bead blasted. Also the matching valley cover clean and primed for painting. Looking to get $700 for both and that includes shipping. Shipping out of Virginia. -Zach
