I'm doing a COMPLETE teardown of the 4.0L and I'm extremely paranoid about any surprises I might have after giving this engine a bath. I'm extremely comfortable modifying components in the block but the head is quite serious. Anyone can throw together a 4.6/4.7L monster by swapping a few engine components but I want to redo the entire thing from top to bottom just because I'm sick of fighting my grandpa and everything he did to my 4.2L that eventually led to it overheating and blowing up.
Just to clear up any vague points, all you need to really know is that I've fought an engine non-stop because of "professional mechanic" noise and once I get this engine built, that's the end of that noise. If it blows up, my fault. If not, I don't have to put up with harassment from my family anymore. There's a sort of validation thing in there but mostly, if anything goes wrong with it, I'll immediately understand what and why.
Right now the plan is to remove everything non-essential to the engine, get the block and head in the hot tank and then start measuring, boring and building. I can't afford to lose momentum anywhere in this process because my time is so precious. I should have been finished with this engine and out of this dump last year. I have until the end of this year and if I screw this up I'm done with the car, as in just pancake it.
