I'm not poo poo'ing your thread... I really am curious why spend that kind of money on one truck?
If your just looking for a serious basher and you have extra dough to throw at it, you need to determine if you want to go big block or stay with a small block. If you go with a true big block, you will need a new chassis just to fit it in. If you want to go with a drop-in BB, you won't need the chassis. If you do go BB (drop-in or not) you will probably want to fully RRP the trans gears, get good cvd's all around, get FLM diff cases/bulks (hybrids) and install 1/8 scale diffs.
Find a decent roll bar/cage (NewEra 3-point was a solid one). Then, if you have $300 to spare go with titanium arms by flextek.
