Hi people, I bought a 86 D150 with a 5.9 360. On the valve cover there is a white oval sticker that has the numbers. 180 on it. What does it mean? I saw some valvecovers for sale that had a similar sticker on it, different numbers.

 

I don't know but there might be someone else on here who knows. All I can say is welcome to the forum.......

 

You got me ????????????????
