Lift stop cable unit

[Bill Rose]

I recently picked up an nos lift stop cable unit (#325875), that I'd like to put on my 69 l-78 El Camino. Does anyone know the story behind this unit. Was it a recall that certain cars got for torque problems/broken motor mounts etc. Were they used on all big blocks and/or small blocks, solid lifter cars etc.

Also: Does anyone have any paper work on this subject, like something from GM or a dealer recall letter, etc.

Any info would be great. Thanks Bill

yes, Camaros, Novas, big Chevies, pickups and vans all got them

Chevelles never did ...

I think there have been posted letters that were mailed on this subject

All were model specific

the holy grail is the one for the V8 Nova, 65-67

not solid lifter specific, but big block / small block specific plus model specific

Are you sure about this? My 66 SS396 Chevelle I bought new had it installed under the recall. I may still have the recall letter from Chevrolet or my dealer, don't remember who I got it from. I thought it was only for cars that had mechanical throttle linkage, and those with cables were not affected?. So a 1968-up Chevelle or El Camino wouldn't have this since they used a throttle cable.

It is my understanding that these were a recall item and were installed on Chevelles also. Why would it be a motor mount problem on every other car and not a chevelle?

[StriperSS]

What I remember is that everything got that under the recall. There was a huge deal made of it in the media at the time too.

The cable carb linkage wasn't as likely to lock the throttle wide open as the solid linkage was.

[GTO_DON]

The reason is simple.66-67 chevelles used the metal accelerator rod which would get stuck under the air cleaner during acceleration when you had a broken motor mount.68 and up chevelles used a cable which stopped the problem

[al8apex]

none of the kits are for &quot;Chevelles&quot; per se, none of the instruction sheets include Chevelles and none of the boxes mention Chevelles

Nova kits, 3 different ones, 1 V8 for 65-67, other 2 are included with the Camaro kits

Camaro / Nova kits 2 different, small block &amp; big block, none for 6 cyl

big car, small block without ps
big car, &quot; with ps
big car, big block
trucks. 2 kits, w &amp; w/out PS
vans

I have never seen a kit that include the Chevelle models and I have had tons of these things (still do ...)

I am sure the reason was the throttle CABLE, vs the ROD as stated above.

Again, I have never seen an instruction sheet mention a Chevelle nor have I ever seen a kit for the Chevelle.

The recall was due to the fact that the driver's side motor mount could break under certain &quot;abusive&quot; conditions, causing the engine to lift on the driver's side, thereby causing the mechanical throttle to be pulled to full WOT condition without the ability to release itself, since it was now at full throttle, causing more of a high-horsepower, torque-over condition, pinning the carb at WOT till the engine blew up, the car crashed, or the driver was intelligent enough to turn the ignition key off, diffusing the impending explosion.

A redesign of the motor mount with interlocking internal plates inside the molded rubber, eventually rendered the recall kit obsolete.

When did the redesign of the motor mount take place? That alone would answer a lot of questions. I know the instructions I had to the recall kit I just sold was dated 1971.

The application on the instruction sheet shows:

1965-1969 Chrevolet Engines left side 396-427.
Except 1969 with air cond AND air injector reactor (A.I.R.)

I'm still not 100% sure it was suppose to go on so many cars, and not Chevelles, but I think it's a cool addition, so I will be putting it on the Chevelle. It's certainly simple enough to remove, if I learn more aboutnitin the future. Thanks formall the responses. BRs

<span style="font-weight: bold">The new anti-lift mount went into use for the 70 model year. (Per the Sep-Oct 69 Chevrolet Service News) </span>
my drawback from using it on a 69 L78 Chevelle is the instructions say except A.I.R. cars

Donnie...Actually the instructions say: With air conditioning {And} A.I.R., because the ac cars with A.I.R had different smog tubes, for the lift stop bracket to fit. So if the car had either AC or A.I.R. it should fit. I tried the bracket, and it does fit around the smog tubes.

[wheelhop]

Well I've already been wrong once on this post but I think the motor mount problem was fixed by the 70 model year.

[69 Post Sedan]

You're right Bill. <<GRAEMLIN_URL>>/biggthumpup.gif I guess it can be taken both ways. So what you are saying is it won't work if you have A/C <span style="text-decoration: underline"><span style="font-weight: bold">AND </span></span>A.I.R.

I think everyone thought it wouldn't work if you had either one....including myself.

Although I did see a couple of Chevelles in our group at the MCACN show that had them installed.

It was a total bandaid solution to a major recall issue. As if the block bouncing up and down is good for the drivetrain or acceptable to the customer.
Chaining the block down instead of putting in new mounts = cheap bandaid.
Put in the good mounts and leave the chain on the dog....

[al8apex]

ok, I knew I had some pictures

Here are the differences between the BB B body kit and the BB F/X body kit, just the ONE cable, that is it!

Note how Chevelle is not mentioned ... and t<span style="font-weight: bold">he date on the bottom of the instructions is December 23, 1971</span>

I was intelligent enough to shove my foot under the gas pedal and unstick the WOT! (High school, 1979, driving my buddy's stock L35/M40 '67 SS396 Camaro. That's how we learned the engine mounts were broken.)

An unfortunate piece of triva .. for those of you that remember the movie , &quot; remember the Titans&quot; it shows Gerry Bertier getting broad sided in his Camaro . That movie was unfortunately only loosely based on fact . The accident was caused by the motor mount issue and WOT . Because of this accident with Bertier we have laws in this country championed by Gerry that help make public place more easily accessible for those in wheel chairs. From Wikipedia

On December 11, 1971, Gerry Bertier attended a banquet honoring the players of the 1971, T.C. Williams Titans football team for their undefeated season. After the banquet, Gerry borrowed his mother's new Camaro. Bertier lost control of the Camaro and crashed into a utility pole. The cause of the accident was determined to be a mechanical failure in the motor mount of his engine[1]. Following the accident, Bertier was rushed to the Alexandria Hospital in critical condition. After initially stabilizing him, the doctors determined that his lungs had been pierced by his sternum, which went into his spinal column.[5] Because of the severity of his injuries, Bertier initially had to be operated on in the X-ray room, only moving to the operating room when he was stabilized.[5] Although doctors tried to relieve pressure on his spine to help him regain some feeling, it was unsuccessful. Bertier would live the rest of his life paralyzed from the waist down.[5]

A month after the accident, Bertier accepted an award for being the most outstanding defensive player in the metropolitan area, a ceremony he arrived at in an ambulance. Bertier had difficulty adjusting to paralysis and life in a wheelchair, confessing to assistant head coach Bill Yoast that &quot;it took him two years to accept the fact from the time of the accident that he would be crippled for life.&quot;[3] Once he did accept it, nothing held Bertier back from helping others. Bertier told his mother, &quot;I don't care if I'm paralyzed. God left me with my brain and I'm going to use it to help people less fortunate.&quot;[5]

During the next year, Bertier coordinated with Alexandria Junior Colleges to set up a &quot;Walk for Mankind,&quot; and encouraged students, adults, company executives to donate. Bertier occasionally met with others who suffered similar injuries, helping them with their rehabilitation. Outside of his hometown, Gerry made speeches across the country for rights for the handicapped. He addressed subjects such as making buildings handicapped accessible. Bertier gained employment with Abbey Medical, selling medical equipment to the handicapped. His position allowed him to attend wheelchair sporting events all over the country.

You must have had one strong foot to pull that motor back down!

[rat tuned]

i have a #325875 nos in the original box with instructions. i bought it years ago to put on my 69 ss chevelle but it would not fit over my large tube headers. i thought it would look cool though. are these things worth anything? best place to sell? ebay maybe? really wish i could have used it as a cool underhood piece. thanx mike

[Bill Rose]

I paid a little over $100 for an nos set-up, in excellent condition. I was happy with the value of the sale. Ebay is probably your best bet. There were a number of others who bid against me.

Thank for all the info guys. I'm a little under the weather, but as soon as I get better I will install it and post some pics.

Thanks Again...Bill

[427TJ]

Bought one NOS-in-box w/instructions for my '67 L35 Camaro. Got it on eBay several years ago for 125-ish.

[kwhizz]

Got mine off Ebay for around $100 when I was doing the Biscayne project.......

I have a s/b with AC one that attaches to the lower compressor bracket. I have never seen one for b/b with AC, but I suspect it's the same, only the cable is a little longer. I considered making a little extension bracket IIRC, need to extend about 1&quot; to 1.25&quot;) to adapt the s/b kit to my b/b with AC car.

Anyone ever seen one for b/b with AC?

[al8apex]

I just noticed that the Camaro &amp; Nova use the forward mounting points from the #3 cylinder and the big car / B body uses the #5 cylinder:

Seems like these NOS kits were 20$ at swap meets in the 80's
