Hi guys, i´m wondering about the cfm rating of Holley carbs. You can buy main bodies and throttle plates from a lot of manufacturers, they say these parts can be used from 650 - 800 cfm DP´s, for example. I do have a 650 DP (list no. 80777) and wonder what causes the differences in air flow capability to the bigger ones if it´s not the main body or the throttle plate?
Maybe some experienced guys can give me some info, Thanks!
Michael
