stock 08' 5.3 everything besides cam and springs. ..
228/232 114 .590ish lift both int/exh
65lbs injectors , dual walbro 255 intank 75% duty if i remeber right
devils own meth kit. duel nozzle
magnum 76mm .96
intercooled, highest iat we seen was 95* on 17 psi
stock 4l80e , stock stall 12bolt . this setup is in a 70 chevelle setup.

ALL RUNS WERE IN 2nd GEAR
3.23 gears
10lbs made 420rwhp 15* timing
14lbs made 540ish rwhp 15*
15lbs and 17lbs it just seemed to stay at 550rwhp 14* timing torque keeped on climbing. it seems to me i have a back pressure problem.. im running homemade log setup.. will be exchanging it for the ebay turbo headers.

the other night bump the boost up.. 2nd gear hit 17ish lbs 3rd it seen 20lbs.. i am pushing water now.. so arp head bolts are already on the way and ls9 gaskets..

i am very happy with how hard this thing pulls.. spins set of 26x10.50 mt streets at 70ish mph.. i kno theres more in this setup..and redewing the hotside will open her up more..

Did u lock up the stall? On Wot. How high can you launch it at rpm wise. nice set up!

yes stall locks up at 70mph wot.. you can see it on dyno chart when it does .. there is no launching the stock stall..lol.. i like to drive it around alot and i dont do alot of digs.. roll racing is more my style. but 2600ish stall with a two step would be sick out the hole.. maybe in time.. im happy with it now..

It makes boost, is a chevelle, and has an LS1. Thats what matters!!

I honestly dont see how the log would be the restriction is what i was getting at. Being a 5.3 and that looks like a 3" log?

I think its time for a decent converter. Should be a blast on the street.

You have one of the largest engine bays on the planet. Just run some truck manifolds.... people have made 2000hp with them.

Also.... please get some real seat belts before you kill yourself.
