A Coyote swap will never be more practical and it would cost $10+k to complete with everything working as it should. You'd be much better off swapping in a 5.3 Big Bore 3V short block with forged internals and throwing some boost on it. Yeah, I know it would add an extra ~120lb over the nose but who cares when you can have 600+rwhp on tap?
What mods did you do to get to 324rwhp & 328rwtq, and do you have the dyno graph?
I don't need/plan on anywhere near 600 hp, but getting closer to, or into the 400s would be nice, but i also want it to be reliable, not boosting into the territory of reducing the life expectancy of the engine, just because i can throw a blower on my little 4.6 and pull 500ish, doesn't mean i want to, or that it would last with me beating on it, which happens invariably. I want a reliable build, respectable power, that i can beat on all the time, and not blow/break **** and have to fix it constantly. I know in the coyote swap the devil is in the wiring/ecu details, getting the gauges to work, other do dads, etc, but there is always hope that someone will release a kit at some point, tho unlikely.
The closest dyno sheet i can find is from years ago before all hell broke loose with the car, some of which is detailed on this site in various threads, electrical problems galore, culminating in total ECU failure during my honeymoon no less, half way to Vegas near sunset point. Long story short, retainer came loose, and allowed harness to mate with exhaust manifold while parked cockeyed on a hill/slant, all was fine when i rolled up and parked, electronics went batshit insane next time i started it, because for the 20 minutes it was parked, the harness melted/welded itself into the exhaust manifold...
Funny funny, i wonder if the electronics problems are me, not the equipment, because my laptops maxtor hdd also died about 3 months ago, which is where my SCT stuff and run files all live. All i have left is the first dynorun i did right after the Earnhardt Ford dealer fixed everything and relieved me of my wallet, making sure everything was working again, running the stock tune. The only mods i had done on the car at the time of this screenshot was literally replacing some broken vacuum lines. So IF there were any unseen mods, it would be something from the previous owner, as i bought the car in mid 2015.
Mods that would be reflected by the newest dyno tuning are, new upgraded fuel pump, new MAF, Roush Intake(minus spacer), axle backs, and like 8 hours of dyno tuning(3 x visits to AZDynoChip) after i got tired of Bama's tunes making my car ping and detonate randomly. Fuel pump was done as it was causing lean outs, not supplying fuel adequately per the dyno guy, my guess is it either was worn out, or else was damaged by the electrical storm that killed the ECU when the harness shorted to the manifold, it appeared to be original on removal so.... New one made a hell of a difference.
