You have mentioned the Holley main jet before. Does this main jet have threads on both ends or what makes it good for a fitting? I really don't know! Once I do understand it, I should include it in the full flow article with a caveat that IF you have a bypass system then....
I got a call the other day from a guy who has a 261 but a 1956 model. He had the spin on adapter and could not for the life of him figure out how he only has 8 pounds of pressure. I told him the original bypass hoses had a 1/8" orifice on one end, so try adding a 1/8 restrictor. He did, and he had 30 pounds and was so happy! So, I want to write the correct information, so this isn't up for grabs. Thanks Jerry!
