23 or 25 engine

[Boody]

Found an engine  and trany ,not sure of year or size. Serial # starts with P23 would that mean it's from a Plymouth and it's a 23 inch?

P23 is the engineering code.

 

Engineering code	Displacement	Length of head	Make	Model	Year
P23	218ci		Plymouth Car	Plymouth 6	1952

 

Flat Head Six Engine Numbers That Start With "P"

unfortunately there is an error in that listing.....it left out the 54 Plymouth 230 six cylinder that was denoted by a diamond...that was the only year Plymouth offered two six flathead 6 engines...both however are 23 inch engines.
