holley carb./ port identification
 

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.

:confused:

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.
