Was the carb installed when the car was built or when the engine was built im still checking dates for parts. Car built bo4 sept 4-engine 0821 Aug 21 is the engine date right. What would be the nearest i could be to the build date and still be ok on the carb. I bought a tim and found no listing for a part number for the CEC solenoid but by checking im sure its 1114444 also have an assembly instructions work book and i havent found the number in there yet. Was the cec solenoid label an issue with the two designs or would both be ok with my build dates. Thanks Chuck

Re: 71 lt1 carb
I'll take the low hanging fruit and leave the 1971 specific stuff to the 1971 people -- there are plenty of them here.
Carburetors were installed at St. Louis -- so the carb date is related to the car build date. For the early C3s the judges generally just look at the trim tag date and use that for the build date. NCRS allows six months prior to, in this case, car build for the carburetor.
In general dated parts should be within the six months before whatever date is the base for the part involved. Window glass is the exception -- 12 months is used there.
Also you can tell the parts that were installed at St. Louis by looking in the AIM (Assembly Instruction Manual). Any part that has a part number listed in the AIM was installed at St. Louis.Terry -
Re: 71 lt1 carb
Chuck,
For your '71 LT-1 carburetor, you need to locate an original with a date stamping of 085.Comment

Re: 71 lt1 carb
Do you still have the CEC solenoid and does your caution sticker run the length of the switch or does it semi rap around it with approx 1/2 from the top and bottom. That was one of the questions i posted and are cars are so close. Do you have any engine photos or can anyone tell me if that detail is important as long as the solenoid is correct. ThanksComment

Re: 71 lt1 carb
It's generally recognized there was an early vs. late version of the warning label on the 1114444 CEC solenoid, but which is 'correct' is rather open ended...
The solenoid was mounted on the carb and shipped with the carb assy from the mfgr (Holley, Rochester, Carter) and both versions (landscape vs. portrait label orientation) were probably pulled at random from what was on-hand at the supplier's plant when a batch of carbs shipped to St. Louis.
Since 1971 is about the end of the line for the use of Holley carbs on Corvette and they were restricted to rather low volume engine configurations (LT1 and LS6), there 'might' be a difference in which version/when of the label/solenoid was on Holley vs. the higher volume Rochester/Carter carbs, but I don't think we REALLY know this tidbit of info...Comment
