I have a 1979 white diesel semi- I have the the vin#-5PRCPG1026690 and the engine block (right side of engine) is cast on the side of the block #218600-It is a big cam because it's cast on the left side of the block. It has one large valve cover on the top.
Still can't identify what type engine is in the truck-if anyone could direct me to a method of identifying the engine it would really help.
I think it may be a cummins engine but I am guessing-help pls
thank you brian
