Default Dyno guesses before tuning tomorrow

I'm getting my car dynoed tomorrow at 3pm, temp should be in the 90's and high humidity. I was going to see how close some of you get to the actual numbers of my mild ls1.

Stock cubic inch LS1
PRC 2.5 5.3 heads
10.4:1 compression
Tsp v2 cam
The hated heat soaked bbk ssi intake
Professional products tb
Long tubes
True duals
SLP lid
UD pulley
Delete cat, rear o2, AIR, EGR
Built 4l60e with 4200 stall
10 bolt 3.23 gear

I know the dyno doesn't matter much, and track numbers are what I care about, but I'd like to see 400 rwhp in the heat with a stalled auto. It will be dynoed on a dynojet.
Any guesses?

I had that exact cam and heads on my old ls1 setup. Never got a accurate dyno run but the car had great mid range power IMO

Not that it'll help much on power, but I do have 42 lb injectors and a walboro pump with hot wire kit. Bottom end had forged rods, forged pistons, moly rings, and balanced. I will be installing a good rearend and drive shaft soon with spray.

I run that pump and hotwire kit as well. It's more than enough at your level but it's not going to add power or anything
