Jon, does that refer to the 4G, and does that also correlate to Waveski's Edelbrock? I don't have an Edelbrock to examine, the pics on the net look like the secondaries could be slightly bigger than the primaries. Almost all of my carburetor experience has been with the Q-Jet due to my 1967, '73, '74, '76, '77, '84 GM trucks were daily drivers, all had V8's with the Q-Jet. My '78 Vette still has the original Q-Jet. I did swap a Thermoquad on to my '67 for a short time since a Mopar buddy let me borrow it but that was back in 1972 and I was still in high school and learning! Aside from a couple of Holly's and installing a new Edelbrock on a friend's truck, it's been Rochester hands-on experience. Thank you for all of your knowledge, stay safe and heal up.
