Wow...awesome to find this thread. This is exactly what I am doing with my car, it just took me 2 years to get the money to get to this point!
KB is also building my passenger log and I plan to do my own crossover. Its funny I asked him about doing it when I first started 2 years ago, but he had not done one for a g body yet.
I don't know if you still read this thread OP, but I have a bunch of questions:
Are you still on the stock rear-end? Did you do anything to it?
Did you build your crossover out of 2" or 2.5"? I was going to go 2" after reading the big thread on velocity on ls1tech, but you are getting great results.
When you say 13 psi on pump, is that truly pump? No water or meth injection?
I see that you have an o2 bung on your crossover pipe just before the KB log...is this the o2 for the driver's side or the passenger side? Are you still running his bung in the log? Do you have another o2 in the downpipe for tuning? 3" or 3.5" downpipe?
Is that a single 60 wastegate?
I own hptuners so I am planning on converting my truck computer to the SD operating system. Did you download one of matt's tunes as a starting point from the wiki or sent your computer to him?
I feel like a total mooch asking this much, but I really appreciate it.

I am using the stock rear with mosser 28spline axles,and disc brake conversion.
my cross over is 2.5in as the vband on the log is 2.5in
1 o2 sensor on drive side, One in the log, and one in downpipe is wideband. the one in cross over pipe near log was welded shut.
my down pipe stars as a 3.5in for the first 1.5 foot then goes to 3in to a 3in dump from a old v6 down pipe.
50mm china waste gate.
Matt lives near by so he came to my house and gave me one of his computers with a tune in it.(Matt is great guy)
I also have hp tuners I did some tweeking and he did some while on the dyno He may have my tune on his wiki page not sure tho.
You can call me if you like.

Sweet. I'd like to hear what she runs!
By the way, are you still running a single walbro 450 pump?

I cant believe I finally found this build thread! I have been looking for more info on this car for the better part of a year, your car is what inspired me to do the 5.3 swap in my own '87 buick. Many of the parts sourced came right from denmahs videos dynoing you car. I had even bought the 78/75 originally and see you have now upgraded! Such an amazingly built car, right down to the two tone paint! I have a few questions for you if its not too much trouble send me a PM!

Nice pass! It's eery how similar are cars are built. My time slips are almost identical too.
Are you planning on a cage?

Wow, that's awesome, not really. Is your weight of 3840 with you in the car, I presume so. I'm at 3800 with my 109 block. I was looking to run low 10s, but my 109 block will crack in half if I try to run at the power levels you're running. I guess I'll shoot for low 11s or high 10s.
Very good job putting this ride together.
I will be going this sat nov 12th
I think i will be putting a 8pt in over the winter. every time i take this car to the track it goes faster. I am going to try a 2deg more timing and more race gas.. that 10.02 pass was 14deg and 19psi ..and try and get it in the 9s on my last pass
