WOW, carbking,,I'm gonna have to read this a few more times to try & get my head around it,,too early in the AM for me. I need a new carb for my 79 Ford 400,,& I have been studying on a Holley 2 bbl(advertised 350 or 500 cfm) for a replacement. Maybe you can also explain my son's Iowa Test of Basic Skills scores also.
