[This](https://forums.giantitp.com/showthread.php?166459-(3-5)What-is-it-that-makes-the-Hulking-Hurler-War-Hulk-so-powerful) seems to be the thread in question. This was a very fun read. With just a little bit of cheese, not even that much honestly, a War Hulk/Hulking Hurler can be brought up to the point of throwing entire galaxies. Several Gurren Lagann references abound.

In short, the build courtesy of Halae in that thread:

Progression

Race: Centaur

This build uses the elite ability score array: Str 15, Dex 14, Con 13, Int 10, Wis 12, Cha 8. All ability score increases are dumped into Str.

Munchkin-Size Me

You can use the standard point buy to max out strength instead of getting the elite ability score array. (+3 = 59)

Belt of giant strength +6 (= 65)

Manual of gainful exercise +5 (= 70)

A runePGtF FRCS of righteous might will give a +4 size bonus to strength and increases your size to huge. (= 74)

A runePGtF FRCS of divine power will increase your BAB by 10. (It, also, gives a +6 enhancement bonus to Strength—which overlaps with the belt of giant strength—and at least 7 temporary hit points.)

At this point 2,863,104 lbs is a light load. So you can throw an improvised weapon doing 14319d6+32 points of damage (50148.5 average; damage reduction? What's that?), and your attack bonus is (+17 BAB, +32 Str, −2 size, −2 improvised thrown weapon =) +45. Anything with an AC less than 48 can only be missed on a natural 1.

Overburdened heave: 28635d6+32 (100254.5 average)

add iron golem arm +12 ac d2 25/+2 +4 con and +12 str ( 92str (when raging)) 4 a +3 lv adust (can be taken at amy time)(give a gauntlet of rust to immune to rusting)
