ren987: in response to the "lighter note" we haven't spent any time tuning yet. We made a small change to the idle as it was PIG rich. The whole thing was so I don't know yet on the idle quality or ease. I don't tune so I won't be able to say how easy it is when we get there. But I can report how is does once its right. ET goals are a 9 sec slip. I have driven the car to 10.90's at 126 full weight with pump gas and the N/A 347 I built. The car was consistent so if I can get the feel on this new setup I think it can be done. Thank you for the compliments.
I am bad about making the cutting comments. I love the f-body. I may have a different respect for my car than most because I bought it new. However I have seen builds on here where the guy has stood the radiator up, dropped the a/c, cut the hood and cowl for a edelbrock intake and big elbow, cuts the nose out of the car for the fmic, makes jokes about going to the dark side by cutting so much metal. THEN dynos this and throws down 585 rwhp. That is what I call butchering. There are alot of nice builds here and then there are those.
I consider my build to be in the middle of builds. Everyone balks at the price of this kit but the time saved not building it and the quality of it are every reason to buy it.

We made a few hits today on the dyno. We've been working through some nasty tuning issues. Finally got though that and the short version is:
724 RWHP
725 RWTQ
10.8 psi
6000 RPM << letting off, trying to take it easy.
17 degrees timing
10.8 AFR
Done on a Dyno Dynamics dyno (most stingy dyno available)
Seems like a decent starting point. I won't be back on it until this weekend. So maybe by Monday I will have something more to show.

Timing was as noted above. Thanks for the compliments and I agree it won't see 900+ at 12 psi. But there is alot left in it. We only have a couple clean pulls done. This is barely roughed in.

Update, 822 HP @ 14 psi spinning the tires on the dyno!
They are working on controlling tire spin.
We may see 900 HP before the day is over.
