I'm probably not going to convince anyone to change their mind about this, but since I started this with my remark, I'll clarify the reason I had for making my original derogatory statement. It was not because of any inherent design or performance defect in the Holley 4160, but rather the fact that ham handed mechanics and untrained owners so often overtighten the endcaps, thereby warping the pot metal castings, that usually, when a 4160 has been in service for a few years, they have developed an incurable internal leak problem. This produces a very poor idle, and a very unhappy owner. Once a carburetor has been warped this way, it is trash; you have to replace the carburetor. This doesn't stop "rebuilders" from processing them and foisting them off on the unsuspecting customer. I personally doubt there is a performance difference between the two choices offered, given that both are adjusted and jetted optimally. My comment had to do with reliability and durability. As if to confirm my feelings, yesterday, I started my 67 Convertible for the first time since just before Christmas, as I had to get at something that was stored behind it. I put a battery in it, pumped the gas one time to set the choke, and cranked the engine for 4 seconds before - - - - varooom! It was running smooth and steady, just as it ran when I parked it. What is the carburetor, you ask? An AFB, still unrebuilt since 1967, dirty and disreputable looking (as is the rest of the engine!). My 64 NY'r T&C often sat for months at a time, and the restart is exactly the same. I think the AFB is the most reliable 4 bbl carburetor ever made, with the possible exception of the WCFB, which I have on many Packards and Studebakers (and my tow truck!) - also a Carter product. This is opinion only, based on many years of playing with old cars, but no scientific study, so don't bother arguing with me.
