I'd like to beg, borrow or buy a few very specific Holley metering blocks.

For testing "variability" (currently, I think there's "quite a bit").


The Holley part numbers I'd like to get my hands on (at least for testing) are:

11180-3

and

11083-6


These were apparently fairly common on Holley 750s in the late 1990s to mid 2000s.

No longer available.


These came from Holley on a 4779-9 / 1620.


Trying to do repeatability testing with a wide band AFR gauge.

Please help if you have any of that sort of thing collecting dust.


I will share anything I find to be "definitive" here - for free - if I ever gather enough info to draw a conclusion.


Thanks,

Mike
