We all care, really 
C'mon now. I don't care if anyone cares. I just want to provide some tech that I rarely see on this site, or any other. I've had my 15 minutes...LOL
The access to the bearing is greatly enhanced due to the fact that the engine is sitting next to the car, not under it!!!
Matt,
The column is from Flaming River. The joints are from Burgeson or Flaming River. I don't remember at this point. Either company can set you up with joints for a stock column or one of their own.
Shaun,
I am a little curious how the LS7 harness will work. The harness will fit, I am not worried about that. I am more concerned about the tune. Word has it that these ECUs are not programmable. Still waiting for the final word on that though.

Today I worked on the rear end. I degreased it and gave it a rattle can make over. Along with the cosmetic touch up I installed new upper control arm bushings and finished up the installation of the weight jacks.
If anyone else is using these weight jacks, I would highly recommend painting them. They are steel with a black oxide coating. I already saw signs of surface rust after sitting in the garage for only 2 weeks.
Tomorrow the rear end will get plugged back in and I will start on the wiring. With any luck, the engine will be going in next weekend.

My wifes change oil light was on for a week b4 I even had time in the garage to get to that! Needless to say not much movement on the Buick/L92 swap!
Though I did get the L92 on an engine stand. And I see a good use for the pallet in your last post.
Keep up the good work Andrew!

I got some 9.5" tall springs, 175lb/inch.
This is what the spring looks like with the car on the ground at the new ride height:
Before, it was 28" from the top of the wheel well to the ground. Now it's at 26". Looks great.
I have to make some sort of rear axle retention strap. Since the car is lowered the shock is too long to keep tension on the spring when the suspension is extended.

It is amazing what difference 2" in ride height makes. The rear seems to sit so much lower now. I am sure part of this is due to the fact that I have tall tires and now they looked tucked inside the wheel well.

Looks Good. I believe you have a 18/295/45? As I recall I ordered the tires I have currently based on findings from your build about 1-1/2 years ago. I liked the 18" wheel with a little bit of sidewall like you have there since the A body has such a big opening. I have been considering going to a 305/35 as I get use to the bigger wheel look, just don't want the rubber band look. Lets see some current full shots of that GTO. Also, you got a fireplace in your garage?

Parts are slowly starting to trickle in. I got the proper cam gear to use with the LS7 cam. I also got a take off C6 water pump.
For the sake of my sanity, I removed the lifter valley cover just to double check that this engine does not have Displacement on Demand. It does not.

Click for full size....(photo credit to Swingtan on ls1.com.au. Could not find the photo I took of my plant)
The front and rear cylinders also have different lifters (on this bank - middle two on the other), which have springs on top and are hydraulically switched on and off via the solenoids through the channels shown in Andrew's other photo above.
Cheers.

I am indeed running 295/45-18s. It is a Nitto 555. The older cars definitely look better with some sidewall. I was thinking about changing over to a 295/35-18 or a 305/35-18, but I don't think I will like how a 26 inch tire will look.
I do indeed have a fireplace in my garage. It seems that the people that build the house back in the 50s, really liked their garage time. LOL

Simple stupid question. What transmission and pilot bushing are you using?
Looks like a TKO, and I thought the TKO had the same input shaft length as a Muncie. The LS motors typically have the T56 bushing which wont fully engage the tremec input shaft.
GM offers an extended pilot bushing for mating a muncie to an LS motor. Which pilot bushing are you using? BTW, I'm planning on an LS/TKO combination myself.

I have been working on getting the wiring sorted out. The GMPP harness has three huge connectors that go to the ECU. In order to fit them through the firewall I would need at least a 3" hole. There is already a 2" hole in the firewall so I wanted to see if I could somehow feed the harness through it. The only way to do that was to start feeding the harness from the inside. With some effort I was able to feed it through. However the huge relay center was not going to make it. So I cut the wires to the relay center. It's no big deal since I will most likely have to lengthen that harness anyway. I would like to mount the relay center on the radiator support so it will not be so visible.
I also fixed some wiring oddities that were done by a shop that did the wiring during the original build. Odd things, like having wires that went from the bulkhead connector fed through the firewall then back out through the firewall, and back to the backup switch. Who does that s**t?
Another thing that I will have to do is get a different pedal. The one that is included with the GMPP harness kit is just plain awful. It is big, and huge, and ugly, and pretty much looks like it's made for semi truck. I think a pedal from a Corvette or a Chevy Malibu might work much better. Maybe a quick trip to the dealership is in order. LOL
