Ford quit sending black 427 Sideoilers to Shelby in '66 and replaced them with the 428 (it was Blue) engine found in a car Ford named the 7 Litre. A Galaxy 500 XL with the 428. It was the only car in the line up with the 428 at that time. It was basically just a bigger 390, said to have 335HP. They were also used in police cars. My mother had one, it ran pretty good. So to cut to the chase, Blue tanks were sent to Shelby with the Blue engines from Ford that were 428's. Black tanks were sent on the '65 and early '66 427 powered cars. So that may explain why there are some who say there is no right and no wrong. That car was probably a late build and had a '66 Blue engine. Nobody knows. Hand built cars are sometimes that way.
As far as the intake is concerned, both the street 427 and the 428 had dual quads on an aluminum manifold, with iron heads.
The 427 Comp. and SC's came with the single Holley 780cfm (Le Mans) carb on an aluminum dual plane manifold and side pipes. Good Luck

Sorry but that information is not entirely correct: Standard production rules for Cobras and Cobra 427's may not be the same as the Mustang based cars produced by SA. Quote from Dan Case from a thread a few yeas ago:
"427 Cobra "FE" engines. I won’t claim to be a 427 Cobra expert but I do help with research for a few original car owners and restorers. I play and study with 1963-65 Cobras but occasionally come up with 1966-67 427 Cobra information.
#1 There was not “an” engine for production 427 Cobras sold retail. I won’t begin to try and drop off into what was possible for Shelby team “company” racers CSX30xx chassis.
#2 The final Shelby American purchase order list itemizes three 427 c.i.d. engines and one 428 c.i.d. engine for 427 Cobra production. The purchase order list doesn’t cover race only stuff and the document given to buyers of racing 427 Cobras with a list of recommended spare parts doesn’t cover entire engines.
So what I have factory documentation on variants wise includes:
1965 Galaxie 8V engines most CSX31xx chassis (automatic transmission also used with 1965 Galaxie 8V manual transmission engine after appropriate parts swaps…at least the surviving original engine assembly tags say so) = black
1966 Fairlane 8V engines in some CSX30xx chassis (standard 427 S/C 2-4V engine) = blue
1966 428PI manual transmission (which must have been super rare even new) engines in most CSX32xx chassis = blue
1967? (I don’t have a picture of an engine assembly tag. The Shelby American original purchase order list doesn’t say what the model year was, it just gives the engine code and description “427 CID 4V Special”. ) 427 4V engines in CSX33xx chassis = blue
Ford “blue” engine paint. No it was not the same every year. Ford started with blue V8 engines for the 1966 model year as far as I have experienced."
I'm sure if there's new info or updates, Dan will comment.
