Re: electromatic clutch questions

The Electromatic was introduced on the 41 models and was available separately or more commonly was sold with OD. It was available thru the 23rd series and was discontinued after the Ultramatic came out. The pre and postwar units are quite different in looks and complexity. Postwar units are much simpler both electrically and mechanically.

You might download the training manual "Clutch and Electromatic Clutch" from the literature section to get an idea of the pieces and mountings for the postwar unit. I can't answer the inter-changeability question right off but the later 327 engine was authorized as factory service replacement for the 356 and many of those 356 equipped cars had the EC.

The power cylinder mounts on a bracket to the side of the block. Not sure but possibly the same holes may have been used for the later engines side motor mount but that is one question. Another question is if the threaded holes on the side of the later heads are present. The control valve bracket uses those to mount. You can look at your engine and the photos to get an idea of locations to check.

If the setup will mount then it is an interesting conversation piece. Not many have seen one -- particularly one that is functional so for that reason alone it might be worth the effort. It works reasonably well once the adjustments are made but does require some fussing to get it dialed in to your liking...and there are times you will find it much easier to turn it off and use conventional clutch in spite of Packard's claims of once the engine was started never having to touch the clutch again.

One downside if the car has more than one driver is there is only one set of adjustments. All drivers have to drive in a similar manner or compromise or suffer in silence if they want to use it.
