Ran 9.89@143.5 on a spinning 1.50 60' even jetting down 50hp.
Here is a run down on the setup:
-FMS Race ported LS6 heads,2.055"\1.60" custom Manley valves
-FMS nitrous spec solid roller cam -? ( not that little 233 cam )
-T&D rockers w\Comp 9990 coated 1.55" springs
-Diamond custom nitrous pistons 13.0 CR
-Eagle H-beam rods
-FMS custom sheetmetal w\dual 58mm T\B
-FMS 1 3\4"-1 7\8" stepped headers w\bullits
-Autolite AR472 nitrous plugs on C16 gas(not N\A friendly)
-STOCK water pump still
-12 bolt w\4.30 gears
-22lb steel driveshaft
-steel flywheel w\RAM 910 clutch
-Stock SS wheels w\275-40 DR's
It still drives good on the street,just a little more choppy at idle. Once I get the trans out and pro-shifited,will be making some more passes in Jan.

Congrats Allan! First 500 rwhp 346ci NA, thats an amazing accomplishment. Someday we need to write down all these LS1 records, so your grand kids will believe you 
Extreme Stock class in the LS1TECH series should be very interesting next year!

I know Brent has the C5 (and overall) record with a 10.58@130.6.
Tough numbers to beat but I think Allen's combo can do it.

Chad,I think Tim is talking about the little ole 418 motor that is doing 580 rwhp with a LS6 intake and stock '98 PCM that can't control the motor after 5400 RPM. Peak HP is at 15.2 A\F 
Will be redynoing with the Accel GEN 7 setup soon,then the intake off my car-will be over 600 for sure

Now that I've seen your mods, I'm impressed still, but not as much as before.
I can't believe nobody caught it, he is running a 13.0 compression which, he is most likely running race gas. Also that nice intake sure helps out a bit too.
I'd like to see what that 346 would do with 11.5 or less compression.
Now let's see that dyno graph.........

Big Daddy Allan Futral, your a bad man!!! WOW, are those numbers impressive. Can't wait to see your track times, should be very fast! I think it's those new pistons in your engine that are creating all the power. Good luck at the track!
