#1 -- SOUNDS AWESOME!



#2 -- I'll never forget my first install of a new LS2 motor --- hitting the key and having it fire and run IMMEDIATELY... it's like --- OKAY! That was pretty kool!

No timing lights - no messing with the EFI - No carb fire drill.... No cam break in... just fire off and run! Gotta love that!

Oh!! I didn't know he was having this built at Steve's Auto Restorations! What's oil for in a new motor? They're supposed to have break in lube on everything don't they?

Getting a lot closer.........Got the Radio all hooked up and installed.......It's the stock AM radio that has been reworked with all solid state insides......AM/FM Stereo and Sirius/XM .......Pretty cool.....The heater/ A/C unit is ready for charging......one problem I had that I knew would be an issue at a later time were the Dome / Console courtesy lights didn't work.....so.....I thought I had something hooked up wrong.......well, today I wanted to get the inside finished up and it was time to deal with that issue.......I had just put some Chinese LED bulbs in those two spots and since they were brand new I never gave it a second thought that the bulbs were no good........LOL.....After checking and replacing the Chinese "Garbage" with regular bulbs everything works just fine.......the only thing that doesn't work out of all the wiring and electrical issues is the console clock bulb..........Got Lucky........Here are some pic's from today.....a long way from a week ago.........The Wheels are finished and are in transit.....so .....we are getting ready for the exhaust system and front end alignment.......

The as-supplied tune from GM is set for 4bar/60psi constant. The controller mentioned above is the FlowWorx kit that can control any of the Gen5 Camaro modules and the CTS-V module to do just that.

For an as-supplied LSA engine either the ZL1 or CTS-V fuel module will work well. If power mods are in the future plans the CTS-V is a better, and in the long run, a less expensive choice.

It's good to hear that the pump stopped after a second or so. Using the ECM to trigger the relay/controller is critical to the health and safety of you and the car. It kills the fuel circuit when no engine rotation is sensed. It is one of the key safety features built into the VaporWorx systems.

I really do like that mounting bracket......

Until the wheels and tires get here .........the car is still sitting on Jack stands..........I've had a major problem I have been chasing for a week and finally figured it out.....After getting the car started and to get the trans filled.......I was going to run the trans thru the gears and get the fluid flowing to set the proper level........as I clicked the car into gear......it started shaking violently.........WTF!!!..........Scared the heck out of me.............I've never had this happen before.......Humm!!!.....I got a brand new driveshaft assy.......Hummm!!!.......So......I start the car again and click it into gear and look under the car.......and the rear axle assy is bouncing all over the place........HUmmm!!!.........So.....I start thinking about it and come to the conclusion that it is driveshaft related..........Now!!!........My drive line angle to driveshaft was a little more than I would have liked so I figured the universals were fighting each other as the pinion angle wasn't set and I thought that maybe I was at that point of nothing was in scync.....So.......I go ahead and raise the back of the trans to get te trans/driveshaft angle down to 3 degree's........Great.........Get everything put back together.....start the car and it still almost shook itself off the jack stands............Shut everything off and get under the car and turn the driveshaft by hand and as it was being rotated it would bind up and after putting some effort into it , it would snap past the bind point and rotate smoothly........did it again and watched the rear axle assy and I could see it moving as the shaft was going thru the "Bind" spot...........Look closer at the rear universal and I noticed that the Universal joint was installed backwards and the raised contoured portion that the grease fitting was installed in was actually hitting the pinion shaft threads........I pulled the driveshaft out and the theads were smashed in about 1/16" .........Duhhhhhh!!!!!..........I got out my little grinder and ground away the contact area.....put the shaft back in ..........started it up and clicked it in gear and ......smooth as silk.........So......I got the drivetrain angle in the "Sweet Spot" and found the problem.....I replaced both universals cause you just never know......Sometimes this car stuff is hard!!!!......LOL
