A very exciting day for me....
 

First let me address the question about gauge size. The gauges I installed were 3 3/8", and it looks like a 4" gauge would fit perfectly. Oh, well live and learn, and now someone gets to learn form this if you try and improve on the idea.

Dash Lights and gauge lights on. I like how this turned out.
sorry for the fuzzy picture

And now for the drum roll, today the motor came to life. Man these LS3's are cool technology. Unfortuanatly the cold air intake routing is not complete so the microphone pics of more from this giant sucking sound of air that any exhaust note, but once this is buttoned up this huge air pump is gonna put some HP to the pavement. The Z06 cam sounds mild now, but can't wait to hear the roar when I take it for a spin. Since she started up now it's time to finish up the interior re-install.
Nothing like the nervous energy from a first time startup, and then she comes to life.:woot:

What a great day!!!!

congrats on getting it running. I like the gauges.

Very nice upgrade..... looks real nice!!!! I was wondering if u could tell me where did u get the fuel fitting on the feed side(out) of the fuel filter/regulator you showed on a pic. The fitting that is a push-on(3/8) on one side and a male -6an on the other. I am installing an LS3 motor I bought from Fesler on a 68 camaro but with an automatic tranny and can't find a fitting for the regulator. Thanks, in advance!:thumbsup:

Fitting on Regulator
 

Russell makes them, do a search at Summit and keyword adapter.

For blue ones here's the part numbers. I still have these and need to return.
640860
640850

Somewhere in my box of receipts are the part numbers for the black ones, but I'm afraid to start searching that box.:lol:

Congrats on the successful install! I appreciate all the detail on the project as I am about to get started on this portion in my car. I also got a LS3 and a fbody 6speed!

The final phase.
 

Well, now I'm tweaking the little things on the interior side which have annnoyed me for some time. Reworked the drivers seat by moving it back some from stock position. 6'2 doesn't work so well in the factory position.

The money shot for me, something about having it back together and so close to getting her done. :)

The bigger money shot. Finsihed the air intake with components from Spectre, 4" diameter. Rubber 90 degree boot from the intake, one straight piece and two 35 degree elbows put the air filter nicely in the drivers side corner of the grill. I'm really happy with how the routing took place, am considering getting the two 35 pieces wleded together to reduce a set of clamps, and then painting the aluminum a matte black color.
Something about the black stealth look I just kind of like.

Now onto the driving impressions. Super smooth on the highway, shifted into 6th gear around 65mph, hit 70mph and noticed the tack at 1600 rpm.:woot:
I must have nailed the driveline angles becasue theres not a vibrtion to be had anywhere, I'm so excited. Motor is 3 degrees down and rear end is exactly up 3 degrees, perfectly canceling each other out. Still taking it easy on the break in, but must confess I got on it around 30 mph and this sucker just flat hauls ass now. I was grinning from ear to ear.

I'll get another video made of the car running now with the hood back on and intake complete. The Z06 cam and dual Magna Flow exhaust sounds great IMO.

congrats
 

:thumbsup:
I like the idea of welding and painting your intake tube ... sounds like you nailed the install....HAVE FUN !!
