first48,

Here are photos of locations of various codes on many high-pressure 235/261 engines.

Where did you find the "VIN", 6fsh2035? How did you decode it to a 1 ton truck engine?

You posted that you found "B50 B48 B50" stamped on the motor. Most likely it is a casted code (not pressed) near the center top of the distributer side of the head? No one has posted information on how to interpret that code.


Bill,

I do not think that you will find any paint information on any code on 216/235/261 engine?
