Hi Ian & Bryan, I know Russ is busy notching his chassis for the extra opposite lock tyre clearance he is going to need so I wont greet him!
Back to the discussion, any test to verify a difference would be best done with a full 8cyl EGT setup and check under part throttle load only- full throttle wont prove anything. If there is a gain to be made here it will be in fuel economy and driveability under road conditons at typical highway speeds.
The GT40 seem's to have it's webers all facing to one side as Ian has mounted his but the Cobra and Daytona Coupe cars have theirs mounted with them facing their respective cyl banks. I assume Shelby supplied the Cobra manifolds which raise's the Question -Did the GT40's prepped by Shelby have his manifolds. Brian I reckon the GT guys were just busy enough dealing with all the other problems sorting these cars without looking for problems of this sort. Thing's like keeping all 4 wheels on the ground and all the gear's in the transmission etc would be paramount. Which makes me wonder about your" If it was good enough for them, its good enough for me." If you copy someone that has done it wrong you seem to get slower, not faster. Would it not be better to look at something and say " yes I can improve on that"
To put it in a nutshell, you are asking one bank of cylinders to drink from the far side of the cup.

Jack.
