408 Stroker

If you know about what CFM carb you want to use and you're thinking of buying a Holley, I'd call Holley first and talk to their techs. before buying. Especially with the new carbs that are out. The new ones are tested dry and the old ones wet.
I'm no expert this is just what I've found out. They told me, if you compare a 750CFM 3310 with an Avenger 770, THE Avenger was really a 680 CFM. Hope this helps.
