Baseline on a head I just built taken at 28 inches of H20.

Intake 295 cfm at 0.500 lift. Exhaust 206 cfm at 0.450 lift.

 

do u know what the flow on the bench was set at?

 

At 28 inches of H20.

 

thanks and this is a stock head right?

 

Yes, the stock baseline.

 

so how does it compare the the 350 head?

 

well its a lot better actually we measured it at 25in of hG but the s2000 heard is way better and that was a holley aluminum e-tec 170 head

 

i can post all the formulas if anyones interested
