Ya know, when I have a question about what cam, intake, head, carb belongs on a combo, I contact a restoration shop that specializes in that make. Your original ,restored, "100 point" 68 Cobra Jet ain't gonna bring the big bucks at B-J with the wrong carb and intake. And your "100 point" 440-6 70 'Cuda with an AAR hood won't either.
Shelbys get to be a different kind of a problem because NHRA considers them a "Manufacturer" in certain years. Which to me means they can basically do whatever they want as long as Shelby will say that "yeah, we built it like that". Kinda like "Nascar" Hemis.

And it took 50 years to finally get the Yenko Deuce in the guide.....
