Patrickt,

Good question. I talked to the Holley tech guy about that; I know that you guys said don't listen to them but...he said that the 600 cfm should be good for this engine all the way up to about 450 hp; the difference I am likely to feel in the higher end rpms between the 600 and 650 is minimal. If I were to be running above 6000+ rpms, then I would be more likely to need the 650; I just don't see 6500 rpm happening with this engine. I'll talk to my tuner about it also though.
