Are the older BBC engines (70 C10 402) free spinning or interference engines?

I’m fearing I broke timing chain. Before tearing into engine I was curious as to what I’m getting into.

Also does anyone know of a good honest reputable engine shop in the Dallas-Fort Worth Texas area.....just in case I need it?
