Now that I have most all of my info, I would like to get some guestimations . I have a 1990 Camaro that weighs in at 3100lbs. The drivetrain consists of a 4000 stall TH350 with a brake connected to a 9" W/4.56:1 heard. So far it hooks like a ****. I am installing a NA LS1 with the following specs. I have all the parts and should have the motor assembled and in the car next week. I am just looking for some similar experiences if they exist.
3.905 bore,6.125 rods and -2cc flat tops
60cc 243's C&C ported by Lloyd Elliott and .051" head gaskets (11:1 SC and 8.47 DC)
The heads flow 287-216@600, 282-209@550, 275-196@500
The cam is Pat G spec'd to 238/244 626" /626" on a 109LSA +2 adv.
FAST 102 unported intake and TB
1 3/4" open headers (I know, but the market is limited for third gen swap headers)
The old setup was the same for the car but a bone stock LS1 down to the intake. It went a 7.54 & 12.004 in decent weather. It dynoed 310 RWHP. The car will be tuned by Pat G once again for the combo so we all know it will be spot on. I am wanting to hear some predictions for HP and ET along with criticisms, good or bad. Although, like everyone including John Force I have a budget so don't be too mean. LOL I would really love to see the car make in the 500+ range and run down in the single digits which I know is awfully optimistic but I have a secret blue weapon if it doesn't work out.

Should go low 10's all dialed in. Maybe a 9 with a bigger stall and if you can lose some more weight out of it. Just my 02

I see low to mid 10's at best with what you've listed

Weight reduction will be the next order of business. I wanted to race it stock one more year and then go turbos but plans change and I had this motor already near built so here we go. Mid to low tens is what I expect but I am gonna shoot for a single didgit pass.

Very similar to my Thirdgen, but I've got a T56.

With the stock engine, I went 7.62@91.5 in the 1/8th. Unopened, bone stock 02 LS1 swap with the Hawk's headers and a tune.

Then, I did this:

Managed an 11.26@122.8 banging the gears, at a 3450lb race weight, driver included.

No doubt if you're lighter and with the TH350 you'll be 10's right away.

Here's the "results" thread.

This winter I switched to Holley EFI and a Tick SNS 2 cam. The smaller cam is way better for street driving, I'm curious to go to the track and see how the ET and MPH change.

Thanks. Though your car is set up quite different, the motor is close to the same build. I was hoping to creep a little closer to the 500 RW mark but it is what it is. My 7.52 1/8th was with the LS1 intake. I could see it picking up a tenth or better with a better intake. I may try it before the new motor goes in because I have hit some obstacles with the new motor.
