Well it's been a long time since an update from this as I needed to take a break of throwing money at it and working a lot of hours and days at work, but I was moved to third shift two weeks ago and that's all it took for me to get my butt back into it.
When I got the car back me and Brandon couldn't get the brakes to stop leaking so I order all new fittings and took the front lines out of the car completely and redid them on the bench compared to in the car. Bleed them and all was good. Mark that off the list.
Next was the cooling system. Since I replaced the radiator and way the cold side routed I had to ditch the stock coolant reservoir And the new rad did not have a provision for the steam tubes. I did some researching and found the 1qt Jaz overflow tanks and ordered one up. I ended up finding some left over aluminum at work and made a decent bracket for me to mount it where the stock one went but was able to clear the cold side. So that solved that. Then the steam port was left. Looked up how the system circulates and found out that placing the steam to the upper rad hose was how it circulate and thank goodness Brandon made a custom upper rad line and I was able to drill and tap it and added a barb fitting and connected right to my steam vent and mark that off the list as well.

So the only mystery I have left is an oil leak that I have narrowed it down to a few things, oil pan gasket, valve cover gasket, opsu or cam sensor. And my turbo feed line was leaking. I will be replacing the valve cover gaskets when I put in some BTR pushrods when they show up. And have already ordered new fittings for the feed line. That will be here tomorrow. While the car is on jacks I have changed the oil again, replaced fuel filter, replacing the trans mount with a poly one.

Now on to the good stuff. I have buying random parts here and there and never got to put them on. But now is the time.
I want to start off by saying a big thanks to JEFF(Hotwire) on doing my rear end.
Current specs is 3.73s and moser axles with ext studs
New specs are 3.42s, solid pinion spacer, new rebuild kit, moser axles with ext studs, TA performance girdle, gear spacer, royal purple gear lube will
Will get some pics up once it comes back.
Out with the old

So now that I have the rear end setup going I decided while it was out it was time to update the rear suspension. So with the car on jack stands I took the non adjustable BMR lower control arms out and replaced them with double adjustable MWC lower control arms along with a MWC double adjustable panhard bar and BMR relocation brackets. Took the stock shocks out and replaced them with strange single adjustable shocks. And to finish it off I got a MWC short torque arm with tunnel mount. And after ordering the torque arm hardware off Kyle at BMR I put an order in for a 25mm rear sway bar with new links and bushings to replace the 19mm and 158k mile worn out stuff. Will get more pics tomorrow

There's a local guy to me that has a SBE LS1 in his Z28 with my old turbo kit and Turbonetics 7875. He's been 6.40's in the 1/8 so far with more room to go.

I should have clarified more I guess. I don't understand why someone who already has a LS1 would opt to go with a 4.8 or 5.3. I guess if you can sell the LS1 and make some money over what a 4.8 or 5.3 costs, but it can't be that much money to be made.
