If so post up what size motor you have and tell us a little about the motor.
Also... if you can post a 1/4 or 1/8 ET that would be Great !!
Thanks

I have a 406 small block, it's a Gen I not a Gen III like your LS3. It runs extremely hard but is still very steetable. It's pretty easy on gas (20 mpg interstate driving) as long as you stay out of the go pedal. All this is owed to putting the right combination of parts together, attention to detail, and spending the time to tune it properly. Details in my signature.

Nice setup ... sounds pretty close to mine. But I have a GEN III motor
what gear are you running?
Any track times?
Have you had your car on the scales?

It has 3.07 gears for now. 3.73's are in it's future. No track times. I raced professionally for years and probably won't ever put this one on the track. I tend to get carried away. It is just for fun on the streets.
I haven't put it on a scale but I pulled quite a bit of weight out of it. Used aluminum where I could. 80's were lighter to start with too.

You can stuff a 4 inch stroker in a Gen III and get 408 ci. Most of the NA stroker motors are usually doing about 11.40 11.70 with solid roller cams.

From: Who says "Nothing is impossible" ? I've been doing nothing for years.
I rolled of the line 2.4 60ft shifted from 1st to 2nd missed 3rd and hit 5th coasted a bit and then finally got it into third and turned 14.1 @ 112mph that's enough for this year. 
My buddy who owns an engine shop says I need a autonatic and should turn low 11's to mid 10's and he never sugar coats anything
