This weekend was the 1st real test for   the LS2. I ran the engine for around 1 hour. The exhaust sounds great. The only problem I had was  a small fuel leak at the carter low pressure fuel pump that feeds the Edlebrock sump located at the battery tray. The other problem was the LS2 thermostat was not opening until 215 degrees. The second fan was coming on at 217 degrees the engine would idle at a constant 217 degrees. I pulled the thermostat and put in boiling water and it opened at 215 degrees. The thermostat says 86 C looks like it is no good. I ordered a new delco 187 degree thermostat. My primary fan was coming on at 210 degrees, I will modify the ECU to come on at 200 degrees. Below is some pictures, the paint is about 60% complete. The color is the original metallic silver from 1971. The vintage air HVAC heater worked great.20181209_123624.thumb.jpg.29513bb8b430a1443ce871806954b80f.jpg

The other problem I had was the fuel gauge is reading empty, there should be around a 1/4 tank of fuel. I installed a fuel gauge from a 280Z, I am reading 39 ohms at the sender. Not sure what is wrong, I grounded the signal wire and the gauge reads full.  I will be trouble shooting this week.

Finished running the AC lines. I ran the two lines to the evaporator through the passenger inner fender. I removed the lower passenger vent. I evacuated the system all went great. Next I will charged the system when the weather warms.

 

I also replaced the gutted power steering pump and replace with a cleaner bracket and pulley from ICTbillet.com

Here are some interior pictures. Just waiting for my new steering wheel from thezstore.com to complete interior.

Hello mrk3cobra,

 

I was wondering what you used for clutch pedal and brake pedal assembly for the t56 swap. Currently have a pedal assembly from a 2002 Camaro and master and slave but was wondering what all you used if you wouldn’t mind giving me some information.

Today was a milestone, I drove the car for the first time around the block. Front and rear sway bars installed, alignment done. Brakes felt a  little soft, car has tons of power. Would like to install power steering in the future. I do not like the angle of the outer front tie rods. Will need to find some adjustable tie rods.

 

The car is 90% done, need to finish blocking the roof and rear quarters.

I had a heck of a time getting mine to cool properly at first as well. I did the same as you, and swapped out the thermostat and still found that I was having issues. I believe the way we're forced to run our upper and lower radiator hoses makes properly burping a bone dry motor quite difficult. What finally solved it for me was adding one of these to the upper radiator hose:

With a 1-5/16" diameter hose and 1/4" steam vent hose size

 

After installing that, I also poured dexcool in the top hose to make sure coolant did arrive at the thermostat, ran it with the cap off, squeezing the upper and lower hoses a bunch, then finally with the cap on but the steam vent on the sight glass opened up to get the remaining air out. I heat cycled it and topped it off from there and haven't had any cooling issues since. I'm currently even running a 25% underdrive pulley and still have no issues!  :-)

I tried adding water to the upper hose, this filled the radiator up above the top hose fitting. I vented the steam vent. I ran the car at idle for around 15 minutes both fans turned on. I measured both  sides of the thermostat with inferred and there was 40 degrees different.  I have a computer hooked up to the OBD-II port and I can watch the temperature rise.
