TAHM KENCH ON HIT. Trying to calculate burst. HELP PLS

Tahm Kench: Sated Devourer Wits End Nashors tooth Randuins Spirit Visage Mobi boots.

I'm trying to figure out roughly how much dmg this build could do.

On hit doubler, stacking dmg/shred x 2, passive.

minor masteries (maxed in: fury,brute force,butcher,feast, executioner,warlord,archmage) and (maxed: enchanted armor, tough skin, veterans scars, bladed armor, juggernaut, hardiness) Attack Speed=base + 40%+50% +50% On hit dmg: at min: +117+15% ap+ his level 6 passive which was +50 atleast. 30% cdr

i thought it could be unreal.

if the community can help thatd be great.
