On the first post, I attached the comparison of both dynos, didnt figure out how to overlay.
The difference are the following:
- Bored .020
- ls7 lifters
- AI cam and heads
- trunion upgrade
- Mufflex 3.5 catback with magnaflow single exit muffler( Old setup was flowmaster catback and also a cutout) Higher horsepower graph is thru cutout)
- 17" wheels, old were 16"
- New level 3 clutch, old was the same
- walbro pump and hot wire kit

Nice results! I've been wondering how yours would turn out given we have very similar combos. Wish you lived close to here as I'd love to line em up. 
Given the torque curve I'm tempted to go with a taller gear for the sake of traction without resorting to drag radials on the street.

Studderin, I knew my headers and intake would hold me back, I convinced myself 420 rwhp would make me happy, so 432 makes me happy. It pulls great, drives like stock and has more power.
My car had low dyno numbers to begin with 405 rwhp with the streetsweeper, there is a tech's vette at new era that did 415 to the wheels with the same cam and slp headers.
If I switch out my LPP headers and y pipe for American racing headers and Y and a fast intake and TB. I bet it will be around 450 to 460 rwhp.
I no longer have any surging under 1800 rpms, I can use my 6th gear again. I would have like to stick with the streetsweeper but it was trashed so mine as well switch it up.

As far as track times, my last setup wasnt that stellar on the track, 12.5 at 113 to 115. Hopefully next winter I am able to put a twelve bolt in with 410 gear and go with a sticky tire.
I am hoping to bring it to the track on street tires this year and see what it does.
We are getting a local track here so I dont have to drive 2 hours to a good track. Should be done hopefully next season.
As far as advance ground in, it says 2.6 degrees. Valve lift is .598 , .600. Just checked my cam spec sheet.

4.10s will be great with either setup, even a stock cam. You don't really hear anyone not liking going to more gear with the t56. That vette has my old SS cam. 
so its gona make more power, haha. Not sure why you had surging in 6th. I could lug the motor form 900rpm in 6th and it didn't surge it was slow as hell but smooth. My new cams like 240 .650 and doesn't surge. I printed out both best setup if you want me to post it, looks a little better then the dot to dot one
you going to NYI anytime soon, go on rochester racing there a bunch of LS1 guys on there that go there alot.I dont think I have any good 26" tire but you can try my 16 with 28 DR, your gona need 4.10 at least

Yup, it will get some upgrades eventually on the headers, gears and intake. Im thinking a twelve bolt first, so I can go to the track with slicks and see how it does. Im actually sick of working on it and want to drive it.
Im happy with the power, on the street I havent been beat yet, but I also havent come across any turbo or supercharged cars.
