Cobrajeff has it right, I think. See my gallery for a view of these installed on a 289. It was a mid 60's Ford option on the Cobra. It mounts 2 Carter AFBs at about 440 cfm each. It's a reasonable setup for the street, seems to run a little rich and I haven't been able to do much about it, but it looks pretty good, and got plenty of punch with all 8 opened up!
