Same impeller, different bearings. Yours has the better bearings as its self contained, so the max shaft speed is 2k rpm higher.

Ok... so the better bearings allow it to be pushed further?

According to them.

Also it has a different internal step up ratio. P600b is 3.05:1 p1sc 4.10:1

max shaft speed 60000, p1sc 62000-64000 depending on model. Same volute, inlet, outlet, etc

I honestly hope at dyno day it performs better, with the way we dyno them there.

See above, I apologize, I'm at work and it's turning into the shining.

Wish Marcel and Joe were a little more quick with sending the info etc over so I could look at it and post it up here. As long as the afr checks out and everything else is ok, then dyno day and convince osie to get a few soft track runs in to see mph to guestimate better. Unless converter is blowing thru...

Sounds like the converter isn't locking up? I saw that on a heads/cam LS car that put down 323rwhp. Put down like 100 more when the tuner forced it to lock up in HPT.

He flashed the fuck out of it. See video. Now I know why. This happened when I tried to dyno it on a dyno com last year without forcing it to stay in 3rd. Osie camaro dyno: http://youtu.be/Mn9fRdg_pXc

Ok, so 425 is the final number? Thats..........really low, even for a stall/auto setup. Unless he's not locking the converter, that'll make a difference. Lots of slip there. That dyno vid ripped right up the RPM band though after he hit it, quite quickly. My guess is if you took it to a track it would perform a LOT better than a 425 RWHP car (trap speed).
