Unless I'm missing something I could only see up to 500 max-ish non-trans unless I'm missing something.
Machete + Obliv Swarming Shield + Masteries + Shock Master + perfect max enchant set = 410 max.
Base STR damage from Elf that ages from 17->18 with Warrior destiny at level 101/25 with capped STR = 135 max.
At total it's like 545 max assuming perfect roll ancient/wh/sn and the max damage for every enchant slot... which would turn to 640 max in trans.
I was counting levels higher than that tbh lol. Which really seems more than doable lately if you just wanna push the limits of stats. Just for the sake of numbers, figure 150/25, food grind +100 str, and add in metalwares o3o.
