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.

Default 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.

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.
