Re: The one I bought was for L88/ZL1

Here's the Camaro L-78/COPO/ZL-1 anti-dieseling solenoid and bracket Mark's referring to:

I checked. The Corvette idle control solenoid BRACKETS were all unique to Corvette applications. The CLAMP was also used for a small number of other Chevrolet applications (with different brackets).

Re: 68 Carb. Idle Solenoid

Joe,
I am presently watching an auction for a used solenoid and bracket that ends in 2 hours.
Is it still your opinion that these solenoids were NOT used on 68 smallblock Corvettes?
I ask only because I don't want to enter the bidding frenzy if I do not need this part for my car.
Thanks,
Kurt

Hi Kurt,

Here are the bracket & solenoid we've discussing.

This is obviously a Corvette assy.

Here's the bracket & solenoid I bought on eBay.

Well, it's still my opinion that they were not originally used for 1968's. However, my opinion has been "softened" somewhat due to the fact that GM says that they were used on some 1968's. GM says, though, that for 1968 Corvettes, the use of the solenoid (and brackets) was limited to L-36 with manual transmission and C-60. Even at that, I expect that this was a later 1968 feature and probably not used on early cars.

Re: 68 Carb. Idle Solenoid

Joe,
I think you are correct becasue I just looke dagain at the asembly manual and it shows the solenoid for the big block, and also the wire routing for the solenoid is shown only ofr the big block. I can't seem to find anything in print that indicates it belongs on a small block.
The used solenoid and bracket (rust and all) is already at $111.00
Thanks for the quick reply Joe. I appreciate it.

Re: 68 Carb. Idle Solenoid

Steve,
Thanks for the pictures.
The one you bought on e-bay is exactly like the used rusted one that is presently being auctioned off and is now at $111.00
I think we have determined that they were used on big blocks in 68 but not my small block. I just checked the AIM again moments ago and find only big block application.

This is the Holley not Rochester part

This part is for the Holley high rise application, NOT the Rochester carb low rise intake. It will NOT work on your A/C car! The Rochester solenoid bolts under the driver's side front carb mounting bolt, not the intake manifold bolts.

Re: 68 Carb. Idle Solenoid

You have to realize that the AIM that we all have is just a partial set of instructions. There are very few complete AIM's in existance. There are a couple of posters here that have some complete manuals. I have seen one of those and it is probably 2-2/12 times the thickness of the one we all have. So it is fair to say that we do not get all the data that was available.

...It gets better yet...

...my '53-'82 GM Corvette Parts Book says '68/'69(350, 427)....then says '69 427 w/Automatic or HD...I assume(fact I'm sure)that this is both engines(smallblock or bigblock with Q-Jet)that uses this same bracket. Does NOT say anything about an application for "327" in '68...now the book also shows a bracket for '71-'74....hmmmmmmmm, my '74 non A/C with automatic does have one...wonder what the difference is??? I already know, do you???? Would even a judge know???

Re: 68 Carb. Idle Solenoid

I believe the idle solenoid was used in 68 as I recall seeing it in the assembly manual. But, I think it was used only with airconditioned cars and possibly only the L36 as you stated. Terry

Re: ...It gets better yet...

The '71-74 idle stop solenoid had a different geometry with the solenoid held to the bracket via a large hex nut threaded onto the case surrounding the plunger. The earlier idle stop solenoids ('68-69) had a very small front end with no provision for a nut. They were held to the bracket with a clamp surrounding the main case of the solenoid.

Re: ...It gets better yet...

This explination (71-74) is the exact one I had on my (Oct 70 delivery) 71 Caprice w/ 400 sb 400 turbo and A/C. hope this helps. D
