And yes, this is still an option. Ran the Q 5 years on the blazer with mostly good results

anything modern, even a product from those a$$holes is leaps and bounds better than factory TBI on a warmed up engine.
that's what Matt is running with some "cop car" injectors and a custom map he had burnt. You should talk to him....
Maybe I am not thinking of something, but if it's too rich, then the injectors should be plenty big enough, correct? The bigger throttle body may help get more air in, so would an injector pod spacer possibly make a difference too?
Do you remember that I have what I believe is a complete set of Moates cables and a laptop with software? I don't remember how close @wheels87k5 is to you.
Edit: I don't have software to burn chips, or the hardware.
I just looked again and I have the ALDL cable and the Ostrich 2.0 cable.

I was just thinking that the BBC unit has bigger injectors (?) as well as more CFM capabilities.
I would think the cop injectors are actually smaller....
I would use the 350 injectors on the bbc throttle body

Did some SBC tuning with an SBC throttle body and some BBC tuning with a BBC throttle body. Couple weeks of tuning the smaller throttle body on the BBC, but there’s a lot less stuff to tweak when you match them up.
That’s a pretty nice stash.
Only guy I know with that much Q-jet stuff stashed away is my Dad. We must have robbed every q-jet we saw in the boneyards we went to when I was a kid. Took all the jets, rods, hangers. Dad being the OCD engineer, sorted by code and stashed the in a box like that too.
I think you got a good stopgap move until you get the EFI sorted out.

Those are the leftovers from when we were racing Stock Eliminator and Super Stock. No Holleys there lol
Not seen in the picture very well is a chart with the primary jet surface area and the rods surface areas subtracted for nominal jet size
We take our Qjets seriously

We weren't quite that serious. We were just going by the David Vizard book "how to rebuild your q-jet" book. Just needed the details to help dial in a q-jet for a basic 350.
Feels weird to go back to a quadrajet, but if it means it will run right and not have failure then it's the correct move until you get the correct injection.
We had the Doug Roe book. Didn’t really occur to us how insane we were until we went to roller bearings instead of bushings in the automatics looking for .05 on the track
It’s no biggie. Ran a Qjet on the K5 the first 5 years I had it
Yeah but going from injection to carb seems silly.
