I cant seem to find the list numbers on a holley 2bbl carb i took off a ramcharger with a 318. its clearly a bigger carb than mine and would like to put it on my fifth ave but i cant find the list number on it anywhere to look up the flow rate. it came off of a 77 ramcharger with the 318 and takes the 5 1/8 inch air cleaner. there are a few numbers on it but i cant find any to be of any use.
