I love torque

[DarkoStoj]

I got my 66 mustang and after a few weeks of driving it I noticed that after a few weeks of driving it whenever I would hammer it I would get unbeleiveable motor mount flex (the shifter would move an incredible amount). I look at the motor and the turnbuckle used to keep the motor in place was bent a good amount.

hard to tell from the pic, but is very noticable when looking at it.

time to get some better motor mounts.

how the hell did u bend the turnbuckle? I realize that all mustans are old and show some wear and tear but geez.

Time for some tough motor mounts or a turnbuckle with eyelets instead of hooks. Also, there is a thread around here somewhere that shows the stock rubber motor mounts with a bolt through them for strength.

Of course its going to bend. The motor mounts are supposed to flex a little. Trying to prevent it from moving with something rigid like a tight turnbuckle is the equivelant of welding it in with a piece of angle iron. Somethings got to give. Straps, chains, or cables are meant to limit the movement in a certain range, not stop it alltogether. I agree, you need new motor mounts.

turn buckle (eyes) can be pulled open too....

I got a set of good, used TCP solid motor mounts if your interested. Too much vibration through the steering wheel on a street car for me so I took them off. The cheap fix is to drill a 5/16" dia hole completely through the motor mount (steel/rubber/steel) on the driver side only and install a grade 8 bolt with about an 1/8" slack in it. It will limit the flex w/o being seen.

Not the exact same mount as your 66+, but the idea is the same. You won't even need the countersunk bolts. . . .

The motor doesn't have to move. Racers run motor plates - large aluminum plates bolted to the front and or rear of the motor - to prevent all movement. The reason there is rubber in factory motor mounts is for vibration isolation.

One thing I do worry about for the original poster is you're risking tearing up your chassis with all that torque. I hope you aren't causing damage to the car. Hopefully the turnbuckle looks stronger than it is and there's no danger.
