Drivetrain HP limits

If you want brute strength, without the brutal price. your best bet is an np205. unfortunately the 205 has a poor reduction of only 2-1 (same as the d20) there is a 3-1 kit for it, but its not much less than an atlas.

205 and 300 are two gear driven, cast iron case tcases that are known as the strongest in the OEM realm. After that, you are looking at Atlas, Stak, etc. You can buy a used Atlas for a decent price though.
