PI stands for shitbox.

I've been seeing this term "shitbox" used a lot. So I think this kinda goes along with the theme of this thread...

Where did that originate from, and why do you guys call it a "shitbox" anyway?

Paul is the originator of this term of reference towards the 4.6 engine regardless of variation.. His opinion is that its fords worse engine (shitbox) till the Advent of the new 5.0...

hummm... alright. I was wondering because I never saw that term used elsewhere, so I figured it was something exclusive to this forum... just didn't know the origin.

I dont think this is a dumb question at all. I was also curious as to the original of shitbox.

But yes, old 5.0...rules your face.
