327 engine mounting

Post by 40clubcoupe » Wed Jun 15, 2022 1:43 am

The earlier 327 (and maybe 356 engines) had a front-of-engine mounting scheme...a pad under the water pump with a rubber insulator and yoke assembly. Sometime after 1948 the 327 went to a side-of-block motor mount scheme, similar to V8s. My question is : Does the casting for the front motor mounts still exist on the later 327s or did they eliminate it on the new blocks? To simplify the question, can you use a late 327 with side-block motor mounts in a car with an early front-mount 327 ? I see that there was 2 versions of the late 327 also, a 5 main bearing and a 9 main bearing version...which may have yet a different setup. THANKS !

I believe the front mounting parts were bolt on using existing holes to mount a plate. Not sure if they used any existing holes such as water pump or timing cover holes or had special. When the 356 engine went out of production Packard produced a service counselor article with instructions on how to mount a later 327 9 main in place of the 356. Perhaps that article will give some insight to your question as to what might need to be transferred, found new or modified from the old engine to the new. https://packardinfo.com/xoops/html/down ... L27NO7.pdf

I have provided a direct link to the service counselor at www.packardinfo.com but sometimes direct links to literature stop working. If needed go to the site and select the Literature Archive, Service Letters, Counselors and Bulletin category and the article is in the July 53, Vol 27 #7 counselor.

The 9 main bearing 327 was exclusive to the top-of-the-line Patrician but as a unit is interchangeable with its 5-main brother.
