Do you have holly jets in the secondarys, or only in the primarys

I appreciate all the tips. I have it together and ready for testing.
I need to make a new tool for adjusting the air door spring.

Jim, I did get your message.

Primary only....Secondary are very unique tall jets and not readily
exchangeable for anything I an aware.

You can drill stock secondary but start with 131 or larger as approach angle is different on small size.

I would love to find some more original 149 jets!

John,
How many .149 jets are you looking for I have some

Has anyone ever made any jet extensions for the secondary that a standard Holley jet would screw in the end? Might have to get the alcohol jets to get ones that are big enough?

I had a similar thought about the screw-in jet extensions that somebody makes. I'm sure if the height is critical, they could be cut & re-tapped, if needed.

They could be made on a screw machine if there was enough demand? I'm guessing not that many people would need them. Could run them on a CNC lathe for lower volumes. I'd have to dig out my TQs to see what threads are on the jets and dimensional data.
