running a blower on the factory motor can get you there. remember ford racing eclipsed that number n/a in the mid 2000s. with a blower it’s just a matter of having good supporting mods. also livernois isn’t the only game in town. other builders also work on ford overhead cam engines.
5.0 swap vs building the 6.2

the lightning guys were making good numbers with the 2v 5.4 running the 2.3 whipple back in the day. no reason you can’t make good numbers with better flowing 3v heads. with the 5.4 you also have the advantage of using mustang internals that are easy to find.

It will, but not without a reasonable question of durability. Who else is building these engines? I really haven't heard of anyone.

the 6.2 is more robust than the older 2v 4.6/5.4 mod motors. those platforms have been pushed into the triple digit hp range with no issues.

If you are talking stock form, the Gen 2 Lightning had fragile connecting rods.

Has anyone here actually done the 7.3 swap yet?
Livernois 6.6 looks like it's 22k, and supposedly handles 850+ HP without any problems. Figure another 8k for the blower setup, and at that point you should have something that would be pretty angry. The question is this - can the Whipple for the 6.2 even push that kind of power? Would it really be better doing a 7.3 swap with a Whipple to try and get to the same power with non-built engine?

I’m now in a 2018 Gen II Raptor. I previously had two 2013 Raptors, one was stock, one was a Roush Stage II with a smaller blower pulley. The Gen I Roush was likely making around 625hp (was 590, but I was running a 72mm blower pulley making 9.5-10psi at near sea level). My Gen II 3.5 TT with a tuner (E85 and 91), front mount race intercooler, ID1050cc injectors and Ford GT spec spark plugs is making right around 625 hp @20.7psi.
The Gen II is considerably quicker and faster than the Roush. It weighs nearly 800 less lbs and has significant mechanical advantage with the 10-speed. If I had my druthers, I’d have a Gen II (looks over time have grown on me, but still love the Gen I aesthetically too) with a 7.3 Godzilla or 5.0 Coyote. The TT 3.5 is surprisingly quick and powerful, but the sound it makes…ugh. Also, pushing 600+hp and 20+psi on a 3.5 V6, stress per cylinder is considerably higher than on a larger displacement V8. It’s held up great so far and no significant mechanical issues, though my timing cover is leaking oil, albeit not a lot, and I have some coolant leaking from inside of the valley between the intake runners and head.
I will say this. In the 15 months I have owned the Gen II, 13 of which have been modded, I have spent at least 20x more time at WOT than on my Gen I Roush, and I owned it nearly five years. Part of me was hesitant to drive it too hard knowing the 6.2 wasn’t designed for FI from Ford. Part of it also was due to being stranded three times when my serpentine belt would get shredded and/or my belt tensioner arm would completely shear off due some poor design and tuning from Roush. I can get into that more if needed, but I didn’t have the utmost peace of mind with the Roush. It sure did sound mean though. I miss that, greatly.
