My Engine Moved!

[domdart]

Hey FABO, I need some advice. I put a 400HP 340 in my 68 Dart 270. I tried a burnout and got some wheel hop. After the burnout attempt it was hard to push in the clutch. I got home and found that the z-bar was hitting the header and the rubber engine mounts had small tears in both sides. I never knew there was a concern about engine movement. What is the solution? Solid mounts? Torque strap? The Dart is just a weekend driver. Thanks FABO.

I just got done shimming my passenger side motor mount 1/4" to level out the motor. Must be the flimsy rubber used in the mounts these days. Going back to solid motor mounts first chance I get (used them back in the '70's without any problems: without any vibration, etc.)

Put a torque strap on that beast!

Fabricate one one of these.
....
Torque Straps (engine-swaps.com)

Adjust the engine back to the desired location.

Install the strap.

I had one on my Super Bee. I went to the farm store and bought a aluminum turnbuckle. There was a hole in the k member for a bolt and nut and a existing bolt on the block.

oldschool and effective

There are engine mounts that have an internal "keeper" to keep the mount from seperating.

Sounds like it's running right! If you use solid mounts, get a poly transmission mount, too. Would love to see some pics of it.

And someone here was making plates to bolt above and below the mount to do the same thing. I should have bookmarked the thread.

How old are the rubber mounts? If I were you , I would be bragging.

I think it was Moparmatt selling the brackets.

I took a stock biscuit mount, cut off one of the bolts and drilled all the way through it. Put in a carriage bolt so it goes through the whole mount. Motor still sits on the rubber, so not much vibration. Mount can’t come apart, since the bolt goes all the way through. Pretty good hillbilly solution & only cost a buck for the bolt.

Thanks, I should have used "limiter" in my search.

Check out Schumacher's '67-'72 A-Body poly lock engine and trans. mounts. I have Schumacher's on a '70 Sport Satellite 383HP 4 speed....problem solved.

Schumacher is out of business.

Man, I hate hearing stories like that. I really liked their products. Perhaps someone has some old inventory. (?)

I don't think so. Someone is assuming their products. Someone will chime in with the details.

Run a countersunk bolt through the DS motor mount. Simple and unobtrusive.

Exactly. Mine is chained down. Yes....effective.

I bought the Mancini Racing Magmounts. Here is a pic of the failed mounts.

 

[Demonracer]

Yow, you definitely need a limiter if it destroyed the mounts that bad.

That's what I'm using on a 440 and no issues so far.

been a problem for many many years. put new mounts in and chain the ***** down. stay away from solid mounts if possible.
