 17066558 is from '80-'85 Chevrolet and GMC Trucks 454cid Non-California A/T.

 That looks to be a later model Qjet. Not sure if it has the electrical hook-ups or not.

Anyway I found a couple used qjets and need to know about them before I try and buy them.

The codes are 17056502 and 17080213.

Which one would be better suited for my 86? My 86 has an auto trans (TH400 to be replaced by 700R4), and a 4.3 v6, power brakes and steering, cruise control.

 Which one do you think would be better for his application, Cliff?

Cliff Ruggles:
Neither one is really any better, same end result if set up exactly for the application.  The manual trans carb may not have a provision for a TV cable if one is needed.  Both can be set up for electric chokes.

The little 4.3 V-6's had carbs set up with no idle bypass air, and very conservative jetting from what I can remember.

In any case, I'd use the carb in the best shape, and set it up exactly for where it's going to end up.....Cliff

soonertank:
OK, I found and bought a used qjet. #17057204 Got it for $20. I'll have to swap out the jets and metering rods for my v6. What size do you guys recommend for a 4.3 engine?

Cliff Ruggles:
That's a large main airbleed model, I'd start out with the stock jetting, as they are pretty lean right to start with.  We sell every jet number for them, and metering rods if you need to lean it down even more?.....Cliff
