I have an all original six pack setup from an aar. My dad took it off the car in the late 70s. I'm thinking about putting it on my street car for fun. It was an auto aar, so I have the original 4792 center carb as well as my dad picked up 30yrs ago or so a 4791 4spd center carb. My question is, what is the original metering block number? I want to make sure I get it put back with the original stuff. Does the 4791 and 4792 use the same number metering block? What number is it?. I have done some checking into stuff in the last week. I have all the og stuff I just want to make sure my metering blocks are. Thanks

Both use same block,# 6610 A

Old Holley Illustrated Parts & Specs Manual No. 36-51 (1972 dated) shows them both being the same.

34R-6610A is the part number and 6610A would be the stamp number in most cases.
