Jet tech ?

I am just starting to get around to doing a 2 barrel for a '70 350, many people put Holley jets in these things. What is involved? Does the float bowl have to be rethreaded, or do the Holley jets go in OK the way they are? This looks to be a fun project, based on progress so far.Thanks for any info.

I know guys that have run over the 1/4 -28 threads to 1/4 -32..Sounds kind of shaky..Never tried it.
Q-jet, 4G , 2G jets are still readily available.

Re: Jet tech ?

FYI you might be better off using the Rochester jets. They are tapered at the opening of the orifice where the Holley jets are not. There is some difference in the way each flows fuel.
