Yesterday, while looking for some obscure Model A part, I stumbled upon an old set (never installed) of 'Float-A-Motor' rear engine mounts. The kind with the heavy rubber donuts, etc., which are supposed to reduce engine vibration to the car.

Thirty-five years ago I installed a set like these on my '30 Coupe. In the early days (1950's-1960's) they seemed like a useful tool to help dampen the excessive engine vibration of the old stock 4 banger. And they did work.

Now however, with today's often heavily modified / modernized engines (balanced 'B' crank & rods, etc. - 'Touring Engines') I am wondering if there would be a need. The engine in my '31 Coupe has had everything done to it that has been recommended to bring it into the 2014 driving world. It seems to run smoothly to my feel. So even though I have a 'Float-A-Motor' kit for it, I am not sure it needs it.

How do the rest of you feel about these rear engine mounts? Besides the rote of the past, do any of you feel a real need for these 'vibration reducers' on today's balanced and well-tuned engines ?
