Nadir, good luck with this sale bro.
To the question about the 3B engine, no doubt they are khotas. I had the pleasure of taking a short drive with Nadir in his monster, and no, its not a Ferrari, but never felt underpowered. The 3B is a great offroading engine. I was surprised at how much lift the monster had, and you've done a good job by upgrading shackles.
