4.0L HO Jeep Engine Build

Thanks for the info! Another note I forgot to mention is that I'll be running with the AW-4 tranny and the jeep spends about 80/20 percent on pavement and dirt, repectively. So based on that, would you still lean towards the Lunati Cam? I know my first gear leaves something to be desired (2.80:1 or something like that), therefore a little extra torque would be nice, but having the power dissappear at 4800 rpm isn't exactly prime either.

While I was reading this thread I've seen you mention "quench" quite a few times. I understand what you did, but I'm struggling to understand the why. I guess what I'm getting at is, why take material from the block versus shaving more off the head itself?

Btw, I may be dropping in for random questions every once and awhile as I plan out this build. It's going to be quite some time before I can start, but a good solid plan doesn't usually hurt....

Before I recommend a cam, I'll need to know tire sizes and gear ratio's. Once I have that, I can answer your queston.

No matter how much material you take off the head, you'll never move the piston closer to the head to acheive quench, all you'll do is increase the compression. Don't confuse compression and quench, they are completely different entities.

Ask away! That's what I'm here for. :) BTW, the power doesn't just drop at 4800, and it will pull to 5200, it just flattens out after 4800.
