I actually have a 4.2 laying around but I sold the jeep its in to my dad. He just wants the trans. The 4.2 crank without any boring gives you what? a 4.5 I think? But that's a little more radical that I want right now.

 

I was looking at parts and came across these rocker arms. Scorpion racing
Has anyone heard of this brand? They seem nice and are a good price, I just haven't heard of the brand before.
