Default Dyno pull today

We had a portable dyno at our clubs (Corvettes of Buffalo) corvette show in Western NY today. So I had to give it a go. The car pulled 236 rwhp and 340 ft lbs of torque They didn’t record the 1st run just the last 2, the third was down on hp because the car was getting hot.
The engine is stock with 94k miles and the following mods
52mm throttle body
Adj fuel pressure regulator
New Bosch fuel injectors from TPIS
New front Y pipe less the cats
High flow cat
Flowmaster force II exhaust
2200 stall converter
New street strip tranny with shift kit

I was wondering if 236 hp is at the rear wheels what would the flywheel hp be. The motor stock from the factory is rated 245 hp

Here’s the link to the video and the dyno sheet

That figures to about 285-290 at the crank using a 18% drivetrain loss from the automatic, the torque number is going to be screwy since its got a higher stall TC.
