Taking out my engine and found something curious to me. It’s a 1967 350 motor. 11A build date for the car. Engine is numbers matching and I’m 99.99999% positive that it’s never been out of the car. I’ve owned it since 1989 and it had only 32,000 orig miles at that time.
Anyway, as we dig into it, we found a braided steel cable fastened with a bolt/nut on the passenger side. It wraps around the exhaust manifold and through the engine mount. I have no idea if this was original and what it is for.
I attached a pic, but it was hard to get anything decently
Any ideas would be helpful ... e.g., was it original, should I put it back when I replace the engine, etc.
The only thing I could think of was one of those safety cables to keep the engine from twisting or bucking ... but wasn't that a big block thing? I can't imagine putting that kind of restraint on a stock 350 small block engine.
Thanks.

I attached a pic, but it was hard to get anything decent to show the full shape and how it sits against the mounts and such.

The cable was part of a recall that happened in 1971.....I think. For a restoration I would leave it out as that's not how it left the factory....Joe

All 8-cylinder engines were involved in the recall.
The cable on your car is home-made, on the wrong side. It was the left side mount that failed.
-
SBC's were also under the recall for installing the engine stop lift kit. If you use the later design interlocking mounts, it's not needed.

The last 67 I did had the cable on both sides, not homemade. Ends were professionally crimped like the LH side. My 67 only had one on the LH side.

Thanks for the replies. My car was a CA car with A.I.R. in it, originally. The cable definitely didn't look home made. Looked very professionally constructed by somebody.
I only had the cable on one side. It looked exactly like the cable on the right side in this pic and was looped into place exactly like the instructions in the background in the bottom left (around the manifold and through the engine mount) -- the second cable and bracket were not present:

Then, based on people's notes above regarding a recall, I found this brief excerpt online:
Report Date: December 29, 1971
Campaign Number: 71V235000
Component: ENGINE AND ENGINE COOLING:ENGINE
Summary: THERE IS A POSSIBILITY THAT A SEPARATED MOTOR MOUNT MAY ALLOW THE ENGINE TO LIFT, WHICH MAY AFFECT THE THROTTLE LINKAGE, MOMENTARILY INCREASING THROTTLE, POSSIBLY TO FULL THROTTLE.
Consequence Summary: UNEXPECTED LOSS OF THROTTLE CONTROL MAY CAUSE LOSS OFVEHICLE CONTROL AND AN ACCIDENT.
Corrective Summary: INSPECT ENGINE MOUNTS AND INSTALL RESTRAINTS WHICH WILL LIMIT ENGINE LIFT AND ELIMINATE POSSIBLE SECONDARY EFFECTS TO THE THROTTLE LINKAGE DUE TO ENGINE MOUNT SEPARATION.
Indeed, the motor mount on the driver side (opposite where my cable was located) was separated ... for how many decades, who knows!
[...]
And I found this old thread with a lot more information, including the original recall letter from GM. I originally posted this when I was busy removing the engine. I'm now sitting down and have time to research this further. Very interesting stuff. I still don't understand why I only had one cable, instead of the two prescribed by the recall. But, I definitely need some new engine-side motor mounts!!

The guy at GM who came up with the idea for the cables should have never had to work again in his life, since he saved GM about $250MM (in 1971 dollars). $1 in 1971 is around $7 today, so imagine today a guy/gal saving a corporation nearly $2B!
I'd still like to know the story about why my car only had a cable on one side ... something I'm sure I'll never know.

GM/Chevrolet’s attitude and response to this problem has always amazed me. Can you imagine that sort of response (we’ll fix it by installing a cable wrapped around the exhaust manifold) in today’s world to a similar problem?
Also, why didn’t those owners who had this recall performed ask Whiskey Tango Foxtrot over?? Really, the fix is installing a cable?? What’s next, duct tape?
Clearly, IMHO, not Chevy’s finest hour to say the least.

I have survivor cars with 2 and with 1. I feel some installers got lazy and only did one side. And said to themselves, that's good, that will work. And went to the next one.
As far as removing it because it didn't come from the factory that way.... MCACN Vintage Certification does NOT subtract judging points if in place. I talked to Steve S about it, and he said he feels it is part of Chevrolet. Sure, it came later, but Chevrolet did it, developed it, sent the letter, and maybe they even did all the installs. I don't know if any of the work was farmed out. Maybe someone knows... So basically, overall, it's "CHEVROLET"
NOW... we move to Mr. Jerry M Who I have great respect. I asked Jerry; he feels since it did NOT come on the car from NEW, that it shouldn't be on the car. At least during HIS judging. Of course, it can be put back on after inspection.
So there ya have it. 2 schools of thought on the subject. I have 2 cars missing both sides. I bought them and have to get them installed before they go up for sale. I have original dated letters and the envelopes they were sent in. So I want to do it.

A friend's mom drove a 1969 SS 350 Camaro for years and I remember seeing a cable on the driver's side. There were no cables on my neighbor's 1968 Z28, although when he built the engine, we did replace the engine and transmission mounts.
-
Danny ^^ Nicely written.
I also had taken ownership of my 396 car and It did in fact have the pair of devices on as obtained in 1983 by me, SO I took the attitude it was there just leave it on. It does come up in conversation at Car shows with the public and other show goers. I am not concerned about any judging.
-
I owned a 65 Impala SS SB car with a powerglide which had a broken drivers side motor mount. Believe me on hard acceleration the motor did lift and pulled the throttle. Kind of scary when it happened. I got the recall letter but when I took it in they would not install the cable because I had headers, said it was modifyed. This was in 1971 I believe. I also remember cars where the fan would hit the shroud on cars with broken mounts.
-
I bought my first 69 Z-28 used in 72, seller gave me the recall letter. Took it to my local dealer and they couldn't install cables because it had headers installed. They contacted zone office and they had them install new mounts. Must have been my lucky day.
-
From someone who had his engine mount break without that cable in place - it's incredibly scary. Luckily, I had the sense to slam the car in neutral.

so if you have a unrestored original with GM installed safety recall a deduction in points ??? who cares what Jerry thinks,,,,whats next a chastise for a dealer installed replacement engine???? get real
-
And after giving it some more thought,,,,cross ram and headers were never installed at the factory either,,,,deduction of points ????
