For what it is worth, I have never seen anyone talk about the cc's of a Buick port, except Edelbrock Port cc's doesn't tell you nearly as much as flow numbers in cfm. A port can be huge, cc-wise, and not flow well at all. Guess the Chevy people talk in port cc's because it is easier to measure...
Port C.C. If you go to NHRA web site and look up you engine spec. in Super Stock they might have a size and yours will be smaller if stock but not much . Have a nice day Ed
Port CC's is only one measurement and not that important. Minimum cross sectional area is most important. All Buicks have small CC ports as compared to other brands and small cross sectional areas in relation to cubic inches which is why they make so much torque. They have good veocity.
