66 Tri power cfm
 

I'm sure It's been brought up in the past but does anyone know the true cfm ratings for a factory 66 tri power. Also realizing that two barrel carbs. are also rated differently then 4 barrel carbs. I've heard numbers from 700 to 11 cfm.

Theoretically, and converted to compare to 4bbls (the 'different rating' you mention), a '66 is about 850 cfm.


'64-65 set-ups apparently are more like 870 (smaller throttle bore but larger center carb venturi's).
