Answer
Thank you for the kind words on feedback.

The way to tell which engine is in the car is to look for the numbers stamped into the front of the block below the right head.  It will probably have to be carefully cleaned to see them, but look for a "44" or a "43" indicating a 440, or a "38" indicating a 383.  The body tag on the left front inner fender also has this information, but it is in a code, and I don't have the code book.   The W.P.Chrysler club will be able to help with decoding the body tag - the tag also gives the colors, other options etc.

With the 4bbl carburetor, I'm guessing it is the 330 HP version of the 383, which is a very fine engine, powerful enough to get one into trouble if not driven sensibly.

My trip has to go well - I'm driving an old Chrysler!

The trip is to the Imperial club annual meeting in Sacramento CA, about 500 miles from my home.
