Well I'm in the same boat as you. I have a F-150 supercrew with a L drivetrain in it. But I would never call my truck a Lightning!!! People will laph at you if they are familiar with Lightnings at all.

It is a nice truck! And there are tons of upgrades you can do.
I would start with a 4# or 6# lower pulley and a custom tune. That will give you a nice jump in power.
