These numbers do not represent an actuall equasion use only for a trend model
Agree..... That's why I said true CFM which I believe were close to Holley's original ratings. That would make a 4779 close to 750, the HP950 was around 820 and the redesigned Edelbrock could flow 850 using the same test standard.
