I found a post today that discusses jet sizes for older carbed 2100 ultra small early v8's...and found a source for even smaller jets than 46's....evidentley some engines at altitude actually used 38's-44's....it seems that very early carbs prior to 63 used similar jets threads to Holly so if ur swapping jets some schooling may be in order to a very early carb...i have a hunch a 2150 with 46's may be a little rich..some experimenting my be in order..

"Yes sir, according to Mannel, all '63 and prior 2100/4100 carbs used the smaller threaded (Holley-like) jets. From '64-up were the larger Ford-only jets.
Allstate Carburetor only sells the larger threaded jets...I guess Holley jets would work for C3 and earlier carbs if replacements were needed."
