Rochester 2G, 2GC, 2GV 2 Jet carburetor main jet sizes.
Your main jets would have the size stamped on the jet. 63 would mean .063
Any year vehicle could have used more than one carburetor number, each with a different jet size. Please remember that these sizes are original and in no way indicate what they should be with today’s fuel. When the spark plugs burn gray colored, you have the correct jet size.
