I'm the odd one out. I'm running a pair of Holley #1904s off of International 1 1/2 ton trucks. I did try Carter YFs to begin with, though. I supose the main trick is to have them jetted the same, and to have the idle screws set the same. One word of caution; if you use the YF, make absolutly certain that they're both Chevrolet units. Some rebuilders will slip a ford jetted unit into a box for a Chevy. They're jetted very different. Namely, the ford carb is way too rich, even for a single application.
