Wondering what will I do to bench test this engine.

The engine can run, with a CCC-disconnected distributor and carb. Not going to bench test this with an extra ECM plugged in... or am I... Apparently, a disconnected mixture control solenoid on the Qjet will make the engine run very rich. Not sure what a disconnected CCC distributor will do (the 4-wire advance control plug), I guess that will make it impossible to test the engine at different RPMs.

On the other end, I could use (just for bench testing) a non CCC distributor -happen to have a turbo setup. Will make for a better bench testing, but, but but BUT I will need to replace the distributor once in the car, and, well, .... adds unknown variables - is that Turbo module any good, never tried it, bought years ago... what if it does not work, ... blargh.

Think I will just put the CCC distributor in, and make the bench testing really quick - before dropping the engine in the car with the full ECM/CCC wiring plugged in.

Nice project journey!!! After reading all 36 pages...as much as I wanted you to see it through, there's a lengthy read over at gearhead-efi. The project was TBI odd fire Buick v6 that the thread starter couldn't get the "distributor ref pulse" to fire the injectors at the correct time. I can see employing a crank trigger might be the hot ticket.
Thanks for dropping by!

Yeah I quit the odd fire part - had to sell the engine because I moved :) Moved on to a turbo carb Buick V6 - even fire :)

After closer inspection... the CCC carb was not only missing a few screws, but that happened because some "internals" were removed, on top of the vaccum pulloffs and the choke. The pump was missing.

So I am playing with all these rods and tiny parts... using spare parts from retired Qjets & also ordered a few parts from quadrajetpower.com

The CCC metering rods were missing
... compared to my spare Turbo carb which had CP metering rods... so will use similar, a bit richer 440 rods. 🫠

Unsurprisingly, the carb is very clean.

Shelving the carburator until I get the missing parts, should be next week.

Turbo cleaned and installed. Will have to think about what to do with the header-to-turbo pipe. Fabrication required.

Show a close up of the header and pipe. I imagine you want as little restriction as possible but I am no blow through turbo expert. Crazy how small the intake flange is.
