I am going to finally start playing with a Qjet and this is the candidate. From what I’ve read it’s the 800 cfm variety and has the more desirable APT. I found a thread here that stated it came from a 78 350 Pontiac.

1. This will be going on my 68 bird and which has the ram air pans in place. Is there any issue with this late model base plate linkage or the carb itself interfering with the lower pan? Spring return provision ok?

2. This carb appears to have the hot air tube choke design but I plan to use a 69 intake which is a divorced choke deal. Can this carb be changed over to a divorced choke? I read in Cliffs book that it can be converted to an electric choke. Perhaps this is more desireable? I might want to cut off the heat crossover completely as I did with my T2 and I really like the clean look. Also, how many choke pull offs do you need with a divorced or electric choke? This carb currently has two. Again just wanting a Spartan clean look to the whole set up.

3. It looks like this carb does have the provision to mount a throttle stop solenoid which I want to use for my A/C as I already have one in place on my Holley. The solenoid bracket is missing on this Qjet but I have a bracket from a Dualjet that I hope will work?

I’ve never owned or worked on a Qjet. I plan to have a local reputable carb shop do the initial cleaning and basic rebuild including bushing the throttle shaft and addressing the well plugs. Hopefully I can decide what choke I want and they can fix me up with that too. Beyond that I would probably prefer to do more of the modifications listed in Cliffs book myself later. I would like to ask this shop to set me up with a particular combo to start with though. My engine is an 428 (.030), true 10.5:1, iron d-port closed chamber, 240/242 HFT, 2800 converter. Makes about 11” vacuum with the Holley and T2 but it was around 12+” with a 66 tripower.

In Cliffs book recipe # 2 calls for :

.072 to .074 main jets
Tapered primary metering rod at least .029 less than the main jet at the widest point
Secondary hanger G or higher
Secondary metering rods .036 to .048

This is just a starting point as I am a total noob to the Qjet. I appreciate any advise and if there is anything glaring about this as a starting point I certainly appreciate someone pointing that out!
