03 Explorer Swap Vin E engine for K?

[Islander828]

I've got an 03 XLT 4.0 Vin K (flex fuel) with a blown engine - looking for swap, wondering if Vin E (regular) can work in it? And what are the issues, assuming I swap intakes, computer, etc.?

Also interested in info from anyone that has done a 4.0 swap in a 01-03 explorer recently.
