Just purchased a 1981 4 speed and saw there was a solenoid on the hood. Did some research and I understand it was supposed to open a flap of some sort at WOT. None of the information I found had any pictures so I am sort of at a loss as to what is actually missing. Does anyone have a good picture of that area to show what it is supposed to look like?
The car is a little bit of a basket case and this is my first (well, wife's care actually) C3 so I am not sure exactly what is missing. There doesn't appear to be any opening in the hood for a flap like some cars.

82s have a flap. 81s do not.

Purchase the 81 assembly instruction manual (AIM) and the GM chassis service manual. Both will be helpful. Purchase an owner's manual for the 81 if you do not have an original.
That is not on the hood of my '81 and have never seen anything like it before. Quite possible an '82 hood like you asked; although I ave never looked at an '82 hood to know about this flap....but going to look around.
That would indicate 81, correct? The title we have matches the VIN on the windshield and the rivets on the windshield VIN are the flowery kind that I understand it should have. Also, the condition of the VIN plate matches with the condition of the surrounding area. So, it would seem that the Vette was probably wrecked and the hood and rad support replaced by one from an 82?
The car definitely doesn't have a cross fire intake on it, but it also doesn't have the CCC on it either. It has a stock intake adapted to square bore with an Edelbrock 1406 carb and a vacuum advance dizzy. I "came" from the Thirdgen F-body world, so I know a little about CFI.
The other "odd" things about the wiring harness is I can find no sign of the coolant temperature sensor wire. The sensor is at the front of the intake, but no where can I find a spare wire that long nor anything with the correct connector type on it. Same goes for the computer, but I haven't looked too hard for it and am not sure where it would be located on the Corvette. Did the 81 use a different ECU connector than an 82? There is also a spare 4 or 5 wire connector sitting on the driver side about at the middle of the fender. It looks like the windshield wiper connector, but that is already hooked up.
Like I said, the car is a little but of a basket case and it's always interesting as to what happens to cars in 30+ years of people owning them.
I replaced the rotted out radiator support in my 80' with an 82' that I got a good deal on. So, it's possible it was in an accident, but it's also possible the parts could have been changed for other reasons.
the computer will be mounted in the storage compartment behind the drivers seat, you have to pull the "liner" out of the compartment and it's mounted vertically on the wall between the seat and the compartment.
