Born after I noticed the Dire Wolf has both the tonnage and the hardpoints to carry three UAC/20s. Due to Heat Penalties, firing all three at the same time will always overheat you however, so one would have to chain-fire. Apparently, the cLB-20X does not carry a heat penalty, but due to fixed DHSs in the side torsos, it's impossible to fit three of them on a Dire Wolf Also please note this is a "proof of concept" rather than a serious build I would recommend running.
Good if you just want a KMDD. Ammo count would be tight for the builds with any decent armor. BTW 4x UAC/AC/LBX20 series are the first thing I try when my get my hands on a direwhale. In testing ground you can mostly kill a mech in one doubletap.
Definitely fun proof of concept! A serious run-capable version of this build would be something like 2x UAC 10 / 2x LBX 20, or 2x UAC 20 / 2x LBX 10 letting you get 5 tons of ammo for each weapon system (or 6 and 4). Try the 4x LBX 10 (Blast Master). Or, as I like to call it, the Sneezegasm.
Remember that cAC10 and cUAC10 have different heat. This is one of the rare case where cAC10 is useful. You don't have to get the SL, but I find it gunny. For practical build take only 1x SL and more amo. You can even rip out the JJ for more. Oh this: If you can fire upon something you will get a KMDD if it is killed. That said your combat time is really limited.
