I gotta think the Holley decal on the cowl is kind of a gag. I gotta look back at the photo dates and research when the carbs were swapped for the injectors, or if the car was built with the injectors. I'm under the impression that the 10 cars all came carbureted and the injection was done soon after, though there are pics of the mule car injected.
There are lots of pics of Missile VII at melrosemissile.com, too.
Thanks for posting that, it's a great find!
