Slant Six Rebuild Price

Thanks guys! I have another question if ya'll can help me out. I am trying to figure out what year the engine was manufactured. It is blue, so i read on another fourm that blue was the color from 1970- early 1983. There is worn out sticker on the head cover that reads 4387094View attachment 1715393978
on the top deck of the crankcase, between the alternator and the valve cover is a pad that should have numbers / letters stamped into it.
That can be decoded to determine when the engine was built. Although Chrysler lost diligence on the stamping in the later years.

The original slant in my '83 D150 is painted black.
