The 331 Hemi (1951-1955)

Imperial Home Page -> Repair -> Engine -> Engine Identification -> 331

We have two articles posted about the early hemi.  One entitled, 50 Years of the Hemi and the other is Early Hemi Spotter's Guide, both appeared in the November, 2001 edition of Hot Rod magazine.   Both are very informative and a good read for all car enthusiasts who are interested in the early hemis.

Here are some websites that we think will be useful to all you owners of 1951-55 Imperials that have the 331 Hemi engine.  These websites have content which pertains to your engine, but maybe not your body style.  We think you can gain important knowledge about your engines from these sites.  Have fun!!
