Holley Metering Block ?

[NtUrMomsDart]

Does anyone know if the metering block for a Holley 4150 carb is the same as the metering block for the center carb on a 440 Six Pack setup? Thanks in advance for your time!

I see your post is working its way down the list, into the basement, so this is a bump. I thought that carb had a metering plate on it.Or was that the 340s? In any case IDK.

Thanks for the bump. The center carb has a metering block. It's the outboard carbs that use a metering plate.

Do all 4150 carbs use the same metering blocks? I'd think they don't.

Doh! What was I thinking? Of course the center carb has a block.
No theyre not all the same. The 1850s for instance are different from the 3310s.There are several/many different calibrations.I think I have 4 or 5 different blocks in my collection,not including the ones Ive recalibrated.Mine are all interchangeable. I have 2 carbs with 5 or 6 digit list numbers that I havent tried.(I think they start with 80xxxx). They are very lean.

Thanks for all the input guys. I got my issue sorted out with my original metering block. Thanks again!
