On Infernape, Stone Edge provides enough coverage as comared to both Thunderpunch and Earthquake.
Inferanap@Life Orb
-Close Combat
-Flare Blitz/Fire Punch
-Stone Edge
-Swords Dance
Stone Edge is a good move for 'Ape.
Swords Dances gets the sweep up/ Between Flare Blitz and Fire Punch, pick whichever you want. With the Life Orb chipping health away, along with the recoil on Flare Blitz, the damage taken from Stealth Rock and Sandstorm, the damage can really rack up.
There's also this set:
Infernape@Life Orb
Timid/Hasty Nature
-Nasty Plot
-Flamethrower
-Focus Blast/Close Combat
-Grass Knot/HP Rock/HP Ground/HP Electric/HP Ice, Ground, Electric or Ice would be the optimal ones to get if you could, otherwise Grass Knot is good enough.
Nasty Plot is the special side to Swords Dance.
Flamethrower and Focus Blast are good moves.
Watch-out for Focus Blast's poor Accuracy. That leads to the choice of Close Combat.
Close Combat has the same power, but doesn't get the Nasty Plot boost. It does however, have good accuracy. If you plan on using Close Combat, use a Hasty Nature Instead.
Grass Knot is a good option. However if you have a good Hidden Power, use it. Rock, Ground, Electric or Ice would be the good ones to use.
