Pinned Motor Mounts

After separating a motor mount again I knew I needed to do something

I hear that the '69 Bronco mounts have torque limiters or pins going though the mount that limits the movement of the engine. The draw back is this motor mount will also raise the engine in the bay approximately 3/8 to 1/2 inch. This might be acceptable if used in a '62-'65 Falcon, but the '60 Falcon having the smallest transmission tunnel needs all the room it can get with a V8 bellhousing. It should be noted that the 260 V8 could have 6 inch bolt span and the 289-351 has a 7 inch span.

I didn't want the harshness of solid motor mounts on a street driven car. Other than the cruelty of this type mount the vibration from the engine will eventuality take its toll on other parts.

I remembered seeing something very similar to this modification in an old Hot Rod magazine years ago. This modification not only keeps the motor mounts in one piece, it will also put more torque to the driveshaft by eliminating the flex in the OEM mount that is lifting the engine when it is rev. It will make a more responsive drivetrain that will responds crisper to throttle response. You also gain less wheel hop, not to mention less chances of the headers hitting the shock towers due to the engine twisting. With this modification I can now have almost the smoothness of rubber mounts and the strength of solid. I can feel a very slight vibration in the steering wheel with the mounts being pinned, but it is not enough to to be concern it is something that was expected.

I had to open up one of the bolt holes on the left side motor mount to keep it flat and from pressing on the block. This could have pushed the corner of the motor mount into the block and cracked or busted a hole in the block when tightening the bolt.
