- Horse hockey! I don't know about the later Triumph products, but the earlier ones aren't hardened at all from what I can tell. If they are, they certainly aren't in the Rockwell C 53-58 range, which

- You're welcome, but I may turn out to be wrong about the later engines (more often the case than not <g>). But the one I'm working on little by little is from a `70 GT6+. It is possible that some imp
