Hello, I have a stock 1973 Chevelle SS L48 (350 4v) M20 4 speed manual trans. The "Chevrolet By the Numbers 1970-1975" publication states that the correct Quadrajet carburetor for my car would be a 7043203. However, the carburetor on my car is a 7043202. By my observations based on how original the car is, I'd imagine that the carb is original, the attaching bolts, rear vacuum line for the power brakes and such, all look undisturbed and match the general patina of the rest of the engine.
I'd like to know the differences between the automatic version (7043202) and the manual trans version (7043203) of these 2 carburetors. If anyone has the specifics of the manual version 7043203 and could post them, then I can see if my carb has those things (like the primary jets, primary metering rods, Idle cam specs, Idle stop solenoid) and maybe my carb was incorrectly numbered from the factory? Thanks.
Dan this might be the 3rd time for you seeing this since I also put it out on Team Chevelle and V8Buick, hehe.QA
It`s all good.....One can never get enough air time on different web sites
I would say that your carb is indeed original to the car....and I would also say that this was most likely a factory mistake....they installed the incorrect part number carb. I have seen this a few times.
