OK V8 What year is the truck supposed to be?

Using both that suffix code and the casting number of the block you can usually nail it down right.

I didn't study this line for line to see how accurate it is but it is usable info.

The lime book that they refer to is this one https://www.ncrs.org/ok/LIME_BOOK_2018.pdf

CEM shows to be an 80 305 that came with a 4 barrel and turbo 350

Or what year was the engine sold to you as and what is the casting number on the drivers rear
