72 anti-diesel solenoid

[Mike E.]

What part numbers are stamped on the body of these? My guess is that since they were part of the carb assembly and came from Flint, that's the reason they are not in the AIM. Same number for base motor/LT-1/LS5, or different? JG makes mention of them, but gives no numbers. Weren't they also used in 73? There's no mention of them in my 2nd edition-updated 73-74 JG that I could find.

Mike, In 72 did they not use a idle step up solenoid for cars with A/C? I know my 72 air car has a solenoid and will step up the idle.when turned on.

Re: 72 anti-diesel solenoid

1114450 was the solenoid. Long discontinued but application was not limited to Corvette. For several years after it was discontinued you could buy an identical solenoid from Standard Parts. The last time I tried to buy one they were discontinued. Should be plenty of them in the previously used and abused storage yards (Salvage yards)

And, it's not that common to see the number on them if it's an orignal, old car. They usually wore off.

Me either. I'd have to go check the car.

1114450 is what's stamped on the one on the car.P3251854.jpg Sorry the pic is not clearer.

Re: 72 anti-diesel solenoid

I stand to be corrected but the number on Patrick's photo is for the assembly, the number on yours is the solenoid only

Solenoid is the same as far as I know. Only thing I know that is different is the size of the muffler bearings.

Re: 72 anti-diesel solenoid

I believe the correct number for 1972 is 1114450. 1997409 is for 1973 350 and 1997417 is 1973 454.

Ed,

What approximate VIN? Mine is almost #23000.
I would not be surprised if the 1997409 made it on to late 1972 cars.

Is that number one that should be included in the next iteration of the JG? Thanks for the info, Sal!

Note that Ed and I both have the 1997409 on our 1972 cars. I'm not sure how original his is to the car but I suspect mine has been there since Day 1. It has at least been there 25 years.

Are you sure that number on yours is not 1997403? While it's unclear, it looks more like a 3 to me than a 9.

In any event, GM specified 2 different solenoids in SERVICE for 1972. These are cataloged as follows:


1971-72 Corvette (w/ 350, 454)------GM #1114444

1972 Corvette w/Rochester carb------GM #1997409

1973-74 Corvette w/350--------------GM #1997409

I believe the 1114444 was the part number for the contents of the SERVICE part package which may have included other small parts and/or instructions. The solenoid in the box was likely the 1114450. I would expect the same sort of thing for the 1997409 but it's possible the SERVICE part number was the same as on the solenoid.
