Do it! The hardest part is the EFI tuning, if you are a novice to it like me. I enjoy the challenge and learning associate with it, but one can always hire that part out if you want.

I was able to make it out to the track again and unfortunately was only able to make 1 full pass. Not a perfect pass, had a little bog off the line and hit the rev limiter on the 1-2 shift. Overall not too bad, got a new best time.

Its been a long time since I posted any update about the car, but I recently added some new parts that people might be interested in.
First up is the new Bergman leaf spring slider kit and leaf springs:
I'll have some outside pictures soon and more details on how the feel of the car has changed. Previously had Mopar circle track springs and caltrac bars. My initial impressions of a quick drive was pretty positive, but I have some pinion angle changes to adjust for now. I had to remove the 2 degree leaf spring shim and it is almost correct now.
Another change I made was updating the radio and front speakers. Added a wireless Android auto head unit.
Added some 4" speakers to the kick panels:

Here are some pictures of the ride height with the new Bergman spring slider package and Bergman leaf springs:
There are no lowering blocks on the car anymore, just a small pinion angle shim.

Looks low in the back in one of the pictures

Its definitely pretty low. There are two sets of holes on the front spring hanger. This is using the top hole(lowest ride height). I'll be swapping the front springs and adjusting the front height slightly lower as well. So I will just leave the back where it is for now.
As far as how the Bergman springs and slider combo feels driving. Springs feel a bit more firm than the circle track springs. Removing the caltracs bars, I was worried about wheel hop and I am pleased to say there has been minimal if any. I haven't felt it. Once adjusted properly, the sliders really don't make much noise. The car does have loud-ish exhaust, so your ymmv. Overall, the change made the rear of the car feel more consistent in its behavior around corners when getting on the gas, which is exactly what I wanted.
Now the front of the car feels too soft(400 lb springs + 1" solid sway bar) and leans noticeably more than the rear, so I am getting stiffer springs and maybe a different sway bar to address the change.

It took a while to get the parts in and installed, but the final round of improvements are done for this year. The following changes were made:
13" CPP front brakes with corvette hub on a mustang 2 spindle.
2" extended upper ball joint from Allstar.
450 lb/in front coil springs
Made a new splined sway bar with custom arms to give room for turning radius & better roll control.
I used a standard Speedway G-comp swaybar(34" width) which works pretty well for a-bodies. It is basically the same width as our frame rails. The arms are cut and welded g-comp arms with 1/4" steel extensions. That left the option open to get stiffer options later. The current 1.25" diameter .188 wall thickness seems pretty nice so far and didn't weight any more than the standard HDK 1" solid bar. It has roughly double the stiffness per the Addco calculator.
One other thing I tried was using an iPhone app Gyraline to do the alignment after all the front end changes. It was decently effective, its hard to know exactly how accurate it is, but the car drives nicely so far. Probably need to pull the lower control arms off and lengthen them slightly to get the camber settings I want. Thankfully HDK arms have some adjustment in them.
Overall, the the changes aren't massive differences at this point, but it keeps getting better and more modern feeling. Which was the goal. Getting more steering angle was probably the biggest benefit. Parking lot maneuvers are less of a PITA now.
