1965 273 4 bbl intake

Edlebrock Performer can fit, you need to wallow out the bolt angle to the more vertical 65 heads and use some hardened washers under the smallish 5/16 65 bolts. Just lean over a drill. I ran one for at least a year with no leaking like that, but I have a 273-4 intake if interested. PM me. There were no 318-4's that would fit.
