John, I just checked and an Edelbrock Performer version of the AFB will fit the standard Performer manifold without any apparent problems. The carb base appears to fully cover the plenum. Now, about that intake I offered you. I checked it out today and here's what I found: It's casting 3872783 with a date of H 20 5, and according to my MSA-1 documentation it's for a Holley- carbed '66 283 or 327. I put an Edelbrock Performer carb on it and it appears to fit just fine. I don't have a digital camera so I'll attempt to provide a detailed description. Imagine that you're looking down on the manifold with the thermo housing to the front and the distributor to the rear: There are 2 small holes connected by a channel just forward of the front carb ports. It also has 2 water fitting locations; one sticks out to the left just forward of the #2 runner and the other to the right just behind the #1 runner. There appears to be only 1 vacuum port and it's located between the left rear carb port and the distributor clamp bolt hole. The first bolt hole for the accelerator cable bracket is located about 3.25" behind the right rear carb bolt hole and the 2nd bolt hole is 3.25" from the first and sort of in line with the first hole and the distributor hole. It needs a total cleanup but as far as I can tell all the bolt holes are good; I tapped them this afternoon. The only one I'm not sure of is the water fitting hole behind the #1 runner; I don't have a tap or piece of pipe to fit it and the fitting in the hole ahead of the #2 runner didn't want to budge so I didn't force it. I hope this is enough detail. Email me offlist at [EMAIL PROTECTED] and we can hash out the particulars.
