Yes this correct, the S/C 5.4 is going to be the daily driver.. My 99'Lariat
My other 5.4 is just N/A w 32v heads, and I want to bump up comp. and get some better Rods... Just a little garage built project. Thats all. Maybe I can convince my cousin to put it in has 86 GT....along with a huge cowl hood. LOL

Hmm, ok. Here's something that someone I know did. He works for Ford and has done quite a bit of training etc. with SVT so he's had some "inside" scoop.
They took his ('01 I think) ORP and replaced the top end with the top end off a SC Lightning, and added the SC. They suspected that the bottom end wouldn't last with the compression bumped up like it was and they were right. About 10k miles (hard miles) is what they guessed and at 10k it fried. Bottom end had a meltdown. What they wanted to see and proved, was that the standard 5.4 would do fine SD'd but as long as the compression was left alone.
In the Marine world, SCing is huge! The 7.4 that I've got is getting a "freshen up" right now. Heads, cam, ECM etc. Whipple makes a SC kit for mine, but I'm also at 9.5:1 and although you keep it at 2-3 lb's of boost, the engine bottom end just won't last. On the other hand, take a 502 MAG that's already about 100 HP higher, it's got the bottom end but it also has a lower 8.75:1 compression. It's an awesome Whipple engine. Just bolting on the Whipple takes you to somewhere in the 650HP range and reliably. I could get a lot more power out of mine (500HP easy) but I want reliability and I don't want to kill it's lifespan so we're keeping in the 375-400HP range. Again, it's the bottom end that's not built to take more. I could build it to take it, but now we're talking $2-$2.5K more and I could spend that plus what's going into the heads etc. and add that to what I could sell this 7.4 for stock, and build a 600+ HP engine that will be as reliable as stock.
Al that rambling just to say, if your doing that much, you should probably build the bottom end to take it. I'm not even sure that there is much out there in HP internals for the 5.4 so you could. But then again, it may not take all that to make that thing pretty wild in a GT.
It does sound like a fun project. Keep us posted on what you find and what you do with it.
