340 w/ 650 double pumper ?

hell I ran a 450 vac sec. on my 60 over 360 and it ran like a raped ape. Would have been better if I had had a 600 on it but still great. 13.94 @ 104 in 1/4. If you do the math on it you only need about 550 cfm if you turn it 5500. So a 600 would still be a little more than you would need by the #'s.
