I like 252HP/128Atk/72SpD/52Spe on Tyranitar with Adamant, and I like Crunch/Fire Blast/Superpower or Stone Edge.
You do not have problems with Gliscor since you run Gengar, Milotic, and LO Garchomp. Earthquake doesn't hit all too much right now that Fire Blast wouldn't. Pursuit isn't needed, as you could be using that turn to Stealth Rock and room must be made.
Crunch is needed with the attack EV's to 2HKO Bold Reuniclus, Fire Blast hits steels, Stone Edge helps with the genies/Salamence, and Superpower hits Tyranitar/Heatran/Terrakion etc hard. The speed EV's outrun most Tyranitar and Scizor, and you have your bulk maximized.
Fire Blast still does enough to everything it needs to with an Adamant nature.
