just an observation
just got and read the doug roe book on rochester carbs. just wanna say this book is an eye opener as to how well engineered carbs are and this book really opened my eyes as far as understanding what a carb does for an engine. for all of you guys that have qjets this is a wonderful read and i highly recommend it... now i'll never be a lars or anything when it comes to qjets but at least i'll know what he's talkin about

I was also blown away by this book. Almost every page made me think, "wow, these guys were really smart." The other cool thing was that Doug Roe said that he got his start in carburetors at the Eclipse plant in Elmira, NY. This factory is about 1 mile from the house I grew up in and I passed it every day on my way to and from school. It's now owned by Purolator, but most of it is still there.

I read it twice and still use it for references.
An eye opener in that so many minor changes between applications that even D. Roe couldn't list them all - no numbers list in book and no vacuum diagrams. I find i need to use a similar year and make of Qjet to dissesemble to find all the secrets my installed carb has.
They seem complicated for even a carburetor but hey, try and pull a EFI system off a BB truck and bolt it in ur vette.
And since i can still find $5 Qjet cores and $10 aluminum intakes for my Chevy 350, i'll find the time to set mine up along with a spare for the tool box. 
I find the Qjet really has its place on a street driven performance V8 car. Triple primary venturis for great low rpm sensitivity and up to 800cfm for BB's power.
BTW i used D. Roe's advice to create a recirc fuel line for my mechanical pump. No vapor lock while in 110*F stop and go, also maintains 6-9psi without an inline regulator. cardo0
