Your 1963 never came with a V8, so the firewall is going to need to be relieved where the distributor is going to go. If you use B body isolators such as from the Barracuda they will lift your engine above the center link far enough that you don't have to Dent your oil pan or change the center link. The manifold I'm using is a knockoff of the Edelbrock Magnum air gap, it's about $120 cheaper and dual drilled for the old style and Magnum bolt patterns. I bought my headers through Century performance
