As far as an easier swap, I would go with a 5.0. The 5.0 re-uses a lot of the same chassis parts and wiring as the V6, which will make the swap easier. Check out the Cobra clone link in my sig for my swap from a 94 V6 to a 5.0 Cobra.

A 4.6 uses a different fuel system, which means you will have to change the fuel pump and possibly the wiring to the pump. I believe you will have to change the k-member as well, and may have to re-wire the dash as well.

IMO, it's simply easier to switch to a 5.0.

haha sorry, i had to, because many a smartass has said it to me before.
on top of the 5.0 being easier, it also has an infinite aftermarket that is cheaper than that of the 4.6...

I am doing a 3.8 to a 5.0 swap now. everyone I have spoken with favors the 5.0 in performance and ease in installation.

You realize you're asking on a 5.0 forum, right? Not saying we're not giving good advice, just realize that most of us have a biased toward the 5.0, so you may get a different opinion if you ask it on the forum for the mod motor SN 95s.

Course, you'd be a fool to listen to those guys cuz they're all Fast&Furious, fart-pipe running wanna-bes...

A lot cheaper and easier to slap a blower on the V6 you have and call it a day. It would be faster than a stock 5.0 or 4.6.

Still easier to put a V6 back in with a blower.

Correct me if I'm wrong but doesn't the 4.6 models use a hydrovac brake booster also?

5.0 is alot easier.

Not only that but it's easier to make 400hp N/A with a 5.0. Than it is with a 4.6. A hell of alot cheaper too.

Try and find a late model block that is already setup for roller lifters. That will save you a lot of money converting the engine to a roller setup. I know the Lightning blocks didn't come with roller lifters, but the block was already drilled and machined for them.

Yeah, I did heads and cam on a 94 Lightning a few years back. I thought it was odd too. But when you order the cam and lifter kit for the Lightning, it comes with that tray and everything. You just take the flat tappet lifters out, and bolt in the roller setup in just like you would on a 5.0.
