This is just a suggestion; it would never fly as a "rule". Since the search engine will not recognise three characters or less i.e. "cam" ,"ARP", "S1", "T3" and so forth, it would be a favor to future searchers for info to write out at least one key word in a searchable form. Camshaft, ARPstuds, BOVvalve etc. I'll do that from now.
