As mentioned earlier, Blair opted for Weber induction available from Inglese. These are 48mm throttle bores, which flow 635 cfm each for a total of 2,540 cfm. This level of carburetion is more attuned to the racetrack than street. "I would never recommend these 48mm throttle bores for street use," Marvin says. Webers must be synchronized using a unison, which measures manifold vacuum. This gets all eight carburetors to exactly the same idle mixture. When you run Webers, you must think of your V-8 engine as eight individual engines sharing four float bowls.
