Thats a sweet car dude, but I think something aint quite right. You've got a big motor (408), a big cam, killer heads, killer inatke, great carb, decent exhaust, gears , etc, and it runs 12.70's at 110? I would look at the build sheet and just assume the motor would be at or very near the 500 flywheel horsepower level, which would put you around 420 or so at the wheels. That would get you down the track around an 11.00-11.20ish at around 118. Your mph is right in line with your ET so I know you aren't getting much wheelspin on the line. I would guess that the car is running very rich and/or you have the timing pulled out too much for the nitrous which is really hurting the N/A et's.
* the only thing I see that you are missing is a stall converter. Maybe you forgot to list it. If your car doesn't have one yet, GO GET YOURSELF ONE RIGHT NOW! You will LOVE it. I would suggest something in the 3500-3700rpm range by a REPUTABLE company, no ebay crap!

I'm confused as well. The motor came with a dyno sheet that showed it making 495HP on the dyno. I ran the car on a chassis dyno late last fall and it only put down 312 rwhp. OK, I can understand that there was no water pump, no alternator, no power steering, and straight headers on the engine dyno. I also realize that you have to subtract somewhere around 17-20% drivetrain losses. But wtf? Somewhere between the engine builder's dyno and my car I lost 200 hp?? My exhaust is the weakest link. Headman 1 5/8" shorty headers connected to 2 1/2" pipes that Y into 3" and then 3" Flowmaster cat-back system (no cats). THE CARB AND IGNITION ARE THE EXACT SAME ONES THAT RAN ON THE DYNO! Same jetting, same timing, etc. With my 150 shot the car put down 425rwhp on the dyno.
I think you may be right about the converter though. One of my winter projects is a transmission swap. I am dumping the 700R4 and swapping in a Turbo 350 built by a local shop that builds racing transmissions. Supposed to handle 800+ HP and has a reverse manual valve body. They spec'd an ATI 10" Super Streetmaster converter right around 3000 stall. Its all in my garage waiting for my lazy ass to get it done. Either that, or I did not get the motor I paid for. Hard to tell without completely disassembling the whole damn thing. I'm also thinking that cam is kinda lame for that motor. I will probably be looking to do a cam swap in the not so distant future also. Thanks for the help.....

Sounds like you should either do the cam on your own, or do some research and get a better shop
Either way, love the "sleeper" look. Do you always run the stock camaro wheels, or is that just the ones you have your DR's on?

Motor came from T&L Engine Development in NC. They've been featured in PHR and CHP so I thought they were reputable??? Who really knows though.....
I have six stock wheels, 4 have radial T/A's and 2 have MT Drag Radials. I'm all about being a sleeper!! Usually, when I get to the track and pull into the staging lanes, no one even gives the car a second look. After a couple of 11 second passes, a crowd gathers....lol

I toally overlooked the header diameter. Yes those little tubes are hurting you. Go get some 1 3/4" LONG TUBES into a 4" Mufflex y-pipe/cat back. That will open up a good 30 or so HP easy. Re-check the timing. If your tranny shop recommends ATI then I guess give it a shot. I personally won't ever buy a low-mid priced converter. Neal Chance, Art Carr, Vigilante are some excellent choices, but they will run 700+. You get what you pay for with a converter. I would get a 3500+rpm. Your cam wants to run that high, so let it.
