BBC with 0411 Conversion 72 Chevelle
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!
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.

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.

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
Wow, comparing your car to mine, its crazy how similar the work is LOL! We have had just about all the same ideas. Which is great because i am running into some issues and need help!
