Tripple 7's

I just recieved a running 12a engine with the Racing beat Holley intake with a Racing Beat header and mystery ports?

Im trying to find out if I have the 600cfm street port setup or the regular 465cfm stock port setup. Is there any easy way to tell the difference between the two setups.

On the choke horn there should be a stamped number. Thatll tell you which model it is. Then cross reference it at holleys online database.

I think the 465 is for a street port or stock port, from RB anyways? I believe the 600 is for the 13b street port. I could be wrong, wont be the first time! If you really want to know I have a RB catalog at the house and it says whats what. pm me and I will look for you.
