70 Challenger with 340. ****pics at bottom of post****
My speedometer cable is binding as a result of my 518 OD install.
I need to keep the engine from "rolling over" under torque.

I'm thinking a torque strap would do the trick. Probably would be an easier install compared to a solid motor mount.

I'm open to all suggestions, what do you think?

I took a measurement, made a strap out of a winch cable...

Trimmed it to length, had the 'eyelets' crimped...

Bolted from K-frame to block...

Allows some movement at the mount, but in the event of a failure, it ain't gonna eat the shroud...

I use a motor mount on the drivers side built to limit the travel. Mancini has them and does Schumacher. It's not a solid mount, just locks up after the motor tries to lift on the driver side.

I definitely vote for torque strap. I tried solid motor mounts and it felt like my teeth were going to rattle out. Way more vibration and noise. I used mitey mounts and Schumacher torque strap. It was kinda pricey, but it has worked well for me.

I made mine out of 1/4 cable, and swaged it. I went behind the battery cable on the head, and K frame, nobody notices it.

cause you only need one on the drivers side the other side leave the stock one on....

I just use a turn buckle from the hardware store. Bolt one end to the head and use a long bolt to the K member on the other end. I leave about 3/4" slack between the bolt head and the K member. That way I can watch the Shaker move, but have the security of a solid stop. And there is no vibration that way, either.


Master, again and still

O.K., how far does your engine have to roll to bind a speedo cable?I'll bet that's not the cause of the cable binding.

You know I have read posts where people have put a solid mount on the drivers side and a stock type rubber mount on the passenger side To me that sounds really dumb If the engine is going to transfer vibration it's going to do it through ANY solid mount even just one.Now comes the stress on the block being mounted solid on only one side would put stress on the drivers side of the block Also if you have so much vibration in the drive train your teeth are rattling you need to address your imbalance issues
I have a motor plate in my car with a fore-aft limiter and a solid transmission mount without any vibration issues.

Myself I prefer a solid mount on the drivers side and I have always used a chain for backup even when I used the rubber mount on the drivers side. So I use a solid mount on the drivers side and a cheap piece of shinny chain for backup. I have used the solid mount for years and it has not caused any problems at all. Myself I am not a fan of eng plates on my street car as I rode in my friends with one and did not like the vibration his car had. Now maybe all eng plates are not like that but his sure had alot of vibration. I get barely no vibration from just the one solid mount on the drivers side. Ron

After breaking stock mounts with the Hemi in my Challenger (Shaker, too), I got Schumacher's Poly-Loc mounts & never had an issue after that.
Pricey, but they worked for me.

I did this idea from the dodgecharger.com forum. Cheap and easy to make and seems to do the job:

I used 2 of the support braces from engine to trans.

cut one end off each,, weld together,bolt from head to frame on my truck. not very pretty but been holding it down for 20 yrs now.

I have a turnbuckle on the car and use mighty mounts on the BB truck.

all work well so far but the homemade strap was cheapest to make up and use.

I used Schumacher mounts,the vibration is noticable. Was gonna switch to rubber on the passenger side and sell the extra, but the stud was too long on the only rubber mount I had that was the right thickness (out of four), got tired of fighting it and put both back in. I have a brand new Schumacher torque strap I bought years ago and never mounted. My car came with a chain on the 340 and it looked like crap.

Some of the techniques suggested are...not well thought out. Solid mounts are a bad choice. Based on too many road course laps and lot's of burnouts there are real world results.

With any type of torque strap holding the drivers side - the passenger mount gets compressed constantly and eventually collapses a bit-enough to tear the right side muffler hanger. This problem is visibly evident in pictures of the car under hard acceleration.

The best hardware is the schumaker [sp?] torque strap mounted on both sides of the engine and quality mounts like mity mounts. Yes 2 [two] torque straps as one does not work. The schumaker set up adapts well to the passenger side. Yes it was road course tested and it made a noticeable difference.

I disagree about the solid mount on the drivers side. I dont run road courses but I drive it on the street all the time and I have been doint it for many years with never a problem. I like to leave the stock rubber mount on the pass side as it does seem to help some with the stock rubber mount on the pass side. Like I said though I dont run road course races but I do drage race where I like the solid mount. Ron

Agreed...

After 20 years...

And 20,000 miles of all kinds of driving...


The OEM style mounts, along with a 'custom' strap, is doing just fine...

No way I'd run solids on a street car...

He was out of the Poly-loc mounts for my /6 to B block swap so I opted for the torque strap. It bolted to the motor mount boss and down to the K frame with 2 small holes to drill. Easy to do, rock solid. Inexpensive IMO. Though turnbuckles from the hardware store are like no buck spending by compare and will do a great job.

I also used the torque strap arm on my '73 - 360 - 4spd Cuda. Excellent as well.

I've tried poly style mounts over the years and there's definitely a noticeable vibration with them. No way I'd even consider a solid mount for a street car. I have a poly trans mount in my trans am now, it was 60 cheaper and in stock when I need it, but not sure I'd use one again.
