Hey Greg,
Sounds like you have some new mods goin on over that way.
From what I recall.
The Explorer is a 5.0 roller motor with gt40P heads, gt40 lower intake (with no Air Charge Temp sensor mount) The roller cam is made for more low end toque. Not quite as snappy to rev and falls off a bit before the 5.0 HO motor would. The E cam would fix that though.
Other than that, the bottom end is the same. And it has the distributor gear for the roller cam.
Wish I could go with you guys Saturday. Heathers been a bit ill. And my father and I allready had plans to go to the Skins game on Sunday.
Maybe next year.
Have fun.
Brad
