If I'm not mistaken, I think I saw that McGurk on eBay. It's the big four piece, three carb one - right? If so, that one will bolt up and work on a 216, 235 and 261. That intake will not, however, mate up to your stock exhaust manifold and basically has no provisions for heat either by exhaust or by water. What kind of vehicle are planning to put the intake on?
Tom Langdon runs this kind of McGurk on his 39 Chevrolet Coupe and has adapted a water line to his to preheat the fuel before it enters the engine with a pipe that he welded across the bottom (front to back) which he runs heated water through form the engine to pre heat the fuel. Of course, you don't have to do that. You can run it without the heat, but you will still have to figure on either headers or do something with your stock intake to be able to use it with the intake.
They are good looking intakes and do draw the attention!
