Thanks for the information Mike, it is greatly appreciated.

The Suffix code is definitely "LK". I will try to attach a picture, but I am a new member, but will give it a try.

The engine came out of a station wagon. I wonder if that matters. Either way, the engine is going into my 1965 C10, as I do not have the original engine.

Thanks Again!!!! Great site for information!!!
