Did you try the Holley web site? They have a lot of info and numbers on there but it is a difficult site to use.

Holley Question Please
 

Are there specific numbers on the metering plates to match to the carburator. This is a 3247 on a 425/427 Vette and they don't match, but neither do my other production carbs. Does anyone have any info on what they are supposed to be.

Re: Holley Question Please
 

I've got an old Holley rebuilders catalog that shows primary metering block as #4901 and secondary metering block as #4519. You didn't ask, but that carb originally came with #70 primary jets, #76 secondary jets, a #21 squirter, and 8.5 power valves in both ends. J.B.

According to "Chev by the numbers". If I'm reading it right, I see "primary metering block stamp 4901, and secondary metering block stamp 4519.
