I had a Dove MR TW so I can relate. But I'm not understanding what you wrote.
First off, this is not in a Cobra right? Way too tall for that??
The part about raising your iron head ports-how did you do that?? Do you mean you have MR heads and you made them fit the HR intake? How?
My SO was a 427" too, had a hair more cam and the Shelby heads pulled 320 at .600 with 2.250" intakes. The difference was a
MR TW with 650cfm, 1850's. It ran 11's and pulled like a freight train.
IMO, the 2" carb spacers are no help at all. You also have too much carb for the cam
and heads. The 750's are only feeding a 427-they're asleep on a small combo like that. They would do better on a 482, 496 or 511 with roller cams.
I'd go smaller to get the velocity up with less additional plenum from the spacers and what ever you have to 'raise' the head ports. Unless you have actual HR heads, you should have a MR TW.
Sorry for not understanding but please clarify.
