Ls2 swap on a V6 I’m doing an Ls2 swap right now and I wanted to know how much power it’ll make at the wheels;
-LS2 SBE
-LS3 Intake
-LS3 heads P&P
-42lb injectors
-Stage 3 btr cam
-Btr spring kit
-New timing set
-Built 4l80e
-3600 Stall
-Carbon Fiber shaft
-Ford 9in Rear 3.23-3.73 gears (depends)
-Possibly ~100-150 shot of nitrous, down the road
My builder suggests that it’ll be ~550 at the wheels just want to see what others got with the same set up.

I think a lot of the dyno numbers will come down to what dyno is used and how the 4L80e was built, the converter and if it's locked on the dyno.
On a honest correctly calibrated DynoJet:
435whp to 450 whp unlocked
440whp to 460 whp locked
525whp-550whp on 100 shot
BTW - quality ported LS3 heads are typically a 25-35 hp gain. Bigger engines might see more. I would wonder about the engine builder's LS experience if he said 50 whp NA for ported heads or 550 whp NA in a stalled auto.
