Unfortunately not yet. Fuel system should be going in this week... and Ill have more pictures. I just don't have the time at the moment but as soon as it gets cold here in NY ill be back on it.
Unrelated to this thread. I'm looking for a set of used L92 heads. I don't mind having them cleaned up if the price is right, otherwise Ill just purchase them new through S&D.
Thanks!

I'm back
Ok, I have ALOT of progress that just happened suddenly. We haven't had an opportunity to work on this car in almost 3 months as we have literarily been in a deep freeze here for what seems like eternity. I have also been busy with work and other obligations. But here is a quick update:
A few changes were made to the setup. We are holding off on the turbo for right now, but the car is being prepared for it which you will see by the way the intake setup is structured. This has been an enormous transformation and an expensive one at that. The rear end setup and 4L60e sucked up the majority of the budget and we have been upgrading parts that were already installed as it continues to snowball out of control.
As of today the 12 bolt Posi has been installed. We had the whole unit powder coated, all new bushings, 3.73 gears, and a Willwood rear disc brake setup installed in place of the drums. I don't have a picture of that specifically but I will get one for the next time I post. We also upgraded the rear with a fully adjustable suspension. The driveshaft was replaced with one again that is something that looks like it came out of a box truck. Way overkill, but it looks awesome. The 4L60e is from FLT Transmission and is their stage 79 (kidding). That's installed as well. Fuel tank has been sumped and -an lines are being installed on both the feed and return side. $900 in fittings, we were mind blown. Complete Rack and Pinion Setup was installed. It was supposed to be a "kit" but it was basically just a rack. So parts had to be sourced from Flaming River for a street rod, and we had to make a center section to hold the steering shaft in place so it doesn't bind. I have to pull the headers and make a slight adjustment to one of the pipes but otherwise we made it work pretty well. The entire car has been wired. I will post a video of that as well. The harness has been modified, as some of the injector plugs were too short, and the cam position wires had to be modified as well because the plug is different from the 97 sensor i'm using to the 2002 which came with the harness. Yesterday we began installing the reluctor. I had to machine the center hub to fit over the arp bolt. Hate on my "machine work" all you like, but it worked and I think its going to mount flush. Now the issue is trying to make some sort of bracket fit as there is no room for the thick CPS sensor to fit between the wheel and the pulley setup. I also have to begin to devise a plan for air conditioning... I have a pump from an 85 Pontiac Parisienne I am hoping to make fit with some custom lines I will need to manufacture.

Excellent project I also will never in the same project load 350 engine and I hope to succeed and do not know whether the pcm 411 needs to be programmed to be compatible with the engine waiting for updates

It will definitely need to be tuned after this swap. I am praying my idea of using a 5.3 tune file for an engine so big will work. I was able to blend the MAF table very easily but I am going to be starting with a very lean MAP table to say the least, they are not even close to being the same layout. Also, hopeful I won't run into "expected air delivery" problems.

Well, I haven't had an opportunity to test fire the Chevelle yet, mostly due to the weather, but I think it's about 98% complete. Just a few small details to button up and it should be ready for a test start/drive. Spent the last week attempting to piece together some sort of air conditioning system. I decided since about 50% of the original stuff is there I am going to attempt to put together an R12 system with a R4 Compressor. I mounted the compressor down low and I'm currently working on some brackets to be able to adjust it. I purchase a Mastercool hose crimper so I could build some custom barrier hoeses.

This was such a PITA... got the knock sensors installed though. The good news is the passenger side fits in the block. The drivers side on the other hand; I had to remove and grind down the motor mount, and then use a 45 degree brass fitting, but I think I got it. Hopefully it doesn't effect sensitivity too much

You can run the the "large" size sensor in the coolant drain hole too...or if you want to go really small like jimmyg suggested....someone makes an adapter to use a gen 4 "small" angled knock sensor in a coolant drain hole also...

GEN IV two wire knock sensors are not compatible with the 0411 PCM
Totally different operations
GEN III are a classic piezoelectric which generates a tiny amount of voltage with vibration and feed directly to the PCM
GEN IV generate a tiny amount of resistance with vibration which reduces the constant voltage from the ECM. They have a feed and return to the ECM

Why bother with the knock sensors at all? The way you have them hooked up they are unlikely to work as intended anyways. My bet is they wont pick up anything, or they will be so noisy that you'll have to tune them out.

I would venture to say you are wrong. Philip has been using them like that for a while and they seem to work. Also those sensors are for a big block, just a 496 instead of a 454. I want to use the knock sensors so I can tune off them. We will see what happens I guess...
