Im looking at an 86 military blazer, and the bottom end went on it. guy said he was pulling through an intersection and it started knocking. said soon as he was through he shut it down. Now my question is, Im on a very limited budget, and junkyards round here are asking a grand or better for a used complete 6.2!!! and all of a sudden all the 6.2 short block assemblies on E-bay are gone! even the 6.5's are gone. what is going on??? and does anyone have a short block assembly for sale??? Id love to have a diesel K-5. Thanx!
