Here recently I've run up on an 03 lightning motor and transmission and was thinking about putting it all into a single cab F-150 4x4 and I have a few questions about the installment...

First, How much horse power would you lose going through the 4x4 transfer case? Would it be enough to actually matter?

Second, is there a better transfer case to use for the application?

Third, would it be better to run a four flew radiator or the stock one?

Would it be best to get the in-the-cab wire harness for the lightning motor or just use the one that comes in the truck. I have the one that goes to the motor for the lightning.

That's it for now. Hope to hear back and thanks to all who respond.
