^I am thinking that the fan is nearly identical, and the main difference is the shroud. That's why I said before I'd like to know cfm ratings for each fan. They obviously had to make a larger shroud to work with the mechanical fan. I don't know how you could test the two, but mine is cooling fine with the stock electric fan and no mechanical fan, even sitting in traffic and such...so I would bet they pull similar cfm numbers, and the only reason there's a difference in design is due to the shroud for the mechanical fan.

Mine is too so far, but I'm also setting up for the 6.1 manifold, which has a front mounted TB and a CAI where the shroud would be.

Yeah I think the real benefit here is the opened up space (if you want it). For example, it clears plenty of room where you could mount a turbocharger or two

Yes removing the mechanical fan frees up a few hp. My point was that I am unsure if having the v6 efan/shroud in place of the stock efan/large shroud (without mech fan) makes any difference cooling wise.
