I'll post a pic of the dyno run next week with exact numbers while I do not have it at hand just now, but some observations of a 3,8l 996C4S conversion. It was customer's car to which we did tuning (for the record I just install and datalog tunes...) including dyno runs at 3rd party dyno.
The car has a GT3 throttle body and 997's fuel rails with injectors, but OEM air filter box and completely original exhaust without any mods whatsover. After the dyno owner started to think about freeing both intake and exhaust... Engine produces a healthy torque of ~400 Nm (295 lbft) but falls on it's face at higher rpm range at only ~340 hp, top of the curve is flat. Numbers are from crank and datalogged MAF #'s are equal.

Pretty satisfying to meaningfully add to the thread. The tuner sent me the graph he saved, its from the 462HP run, we got a little more out of it but lost the graph to computer abyss, so we'll go with 462 for internet bragging purposes. This was on a Mustang chassis dyno
The engine: GM 6.2L L92 converted to LS3 spec with manifold / throttle body / injectors. Engine management is the stock GM ECU modified with HP tuners software.
Go fast stuff:
Katech LS3 Race Cam
PSI Beehive springs
Johnson Lifters
Magnaflow X Pipe resonator
2.5in Exhaust
Garbage shorty headers that apparently can make good power.

Got me curious so I snipped AFR from other guys that included...
Yours...
This is @NYoutftr 's 3.6 - after tune I believe.
This is @Jengah 's 3.8. He didn't mentioned if the engine had a tune on it.
This is the big power run that @BRS-LN posted.... would love to see an owner post something equitable.

These are Schrick Cams, however they were from the original rebuild years ago when the IMS bearing went boom with the previous owner. Bore Scoring issues (what prompted my rebuild) weren't a known issue when the 1st rebuild happened, so here we are with rebuild #2.
Schrick Cams part numbers were noted on 1st rebuild paperwork as follows:
-=-=-=-=-=-=-=-=-=-
Exhaust:
0454A1921-L0
0454A1921-R0
Intake:
0454E141-L0 ** Looking around, I suspect that this part number had a typo. Pretty sure they are actually 0454E1841-(x)0
0454E141-R0
-=-=-=-=-=-=-=-=-=-
The cams, an IPD Plenum, and GT3 Throttle body were all part of the original rebuild. All of which were retained for rebuild #2.
