Metering Block Application

[Robert E.]

Hi All, I have a list 4801-1 Holley with the following metering blocks. Primary stamped 6188 and secondary stamped 5671 and 4609. According to the third edition of the judging guide, they should be 6808 and 4519 for my '71 LT-1.

Can someone tell me what I have here?

Thanks in advance

Robert

I am away from home without my judging guides, but I know there were some recent changes/additions to the Holley metering block numbers. Someone with the latest judging guide may wish to help.

Robert,
My 71 LT-1 is VIN 16789. It's a very original low mileage car and interestingly it has the proper 4801 LIST Holley but has a 082 date(Aug. 2, 1970). Even though it is outside the 6 month window conventional wisdom decided it was original to the car and it passed muster during Flight and Bowtie judging. That said, it has the correct 4519 metering block on the rear but has a 6335 metering block on the front instead of the 6808 mentioned in the Judging Guide. It also has a 6625D ink stamp on it. It's just another example of different possibilities that can exist. Terry may have some additional information on this.
