Thanks in advance.

1968 was, indeed, the first year of the use of a throttle cable on a Corvette.

I don't have a photo of the throttle arm for an LT-1. However, I think it's the same as other Holley carbs of the period.

Here's what my 72 looks like.

Hi Bryan,
Great, clear picture. It's so good it raises a question for me... I thought that '71 cars were the only year that had the CEC Solenoid and had it mounted on that side of the carb. Just Curious.
Regards,
Alan

I'm sure Brian can speak for himself, Alan -- but that is no CEC solenoid. Note the lack of vacuum fittings on the front. That is a throttle solenoid for AC cars. If you look at the very top of the image you can just see the compressor and AC manifold.

On the subject of that solenoid -- what about the screws holding it on??

Alan -Yes, a/c car.

Terry,
As for the screws, are they not correct? If not, what type should be holding it on?
Thanks,
Bryan

Sorry for murdering your name Bryan.

I would have expected hex head screws, but I was hoping someone else with an AC LT1 would offer their opinion.

Re: Need Photo of '70-'72 LT1 Carb Throttle Arm........

If my memory is correct the bolts are unique. They are 1/4" with a 3/8" hex head. Also use a french lock

Re: Need Photo of '70-'72 LT1 Carb Throttle Arm........

I know the 1971 are tht way, but I am less sure of the 1972 w/AC. That is why I asked.

Re: Need Photo of '70-'72 LT1 Carb Throttle Arm........

The LT-1 AC car that we restored had the hex bolts and the lock. Has not been to many years that the bracket, bolts, and lock were still available from Holley. Gone now though.

Re: Need Photo of '70-'72 LT1 Carb Throttle Arm........

Not to worry about the name Terry.
I thought those screws looked kinda out of place.

Thanks Dick for the reply.
It would be nice to one day put this car on a judging field to find out what is correct or not. I've owned the car for a little over a year. I bought it from a guy in Panama City, Fl. who bought it from a guy who brought it down to the Moultrie, Ga swap meet. Unfortunately, my wife threw away the folder that had the Moultrie guys name and telephone number on it. So I'm at a dead end as far as a owner search goes. I know the car spent some time in North Carolina because of the inspection sticker still on the windshield.

Bryan, how current was the NC inspection sticker?

[Bryan M.]

Re: Need Photo of '70-'72 LT1 Carb Throttle Arm........

I think the date is 2000 something.... maybe 2002. I'm away from my house right now, so I can't check it.

Thanks Bryan.........that's just what I needed! Older style linkage won't clear the drop-base air cleaner necessary for use with the LT1's dual feed Holley with center hung floats.

Although there were minor differences among 65-72 Corvette open element air cleaner applications, they all featured similar "drop-down" base configuration. So, the throttle arm for any 1965-72 Corvette Holley carburetor should be compatible.
