Next order of business was electric fan and shroud, and radiator hoses. I chose the 2016-2019 Camaro single SPAL 18" fan. it will be PWM controlled and is a very popular choice according to the internet as it can flow 5000CFM. Although I cut up the factory shroud to "work" I felt like I needed something fancier. modeled up a base to start working from and had my friends at laserbros in NC laser cut and bend it up. Should have gone one or two AWG thicker so added some bracing as well as some mounts and very happy with the final product. Cut down the radiator and inlets and outlets on the engine and welded on some -16an bungs, made up a couple hoses. in the last photo of the "hose installed" you can see the end of the pipe for the intake I welded into the chassis I mentioned in the previous post. Also decided to move the alternator to the other side of the engine to get it away from the heat. When i pull the engine to paint the bay i'll design and make a bracket to permanently mount it over there.

Another pic of the toggle cluster I am putting in my Atlas Z. fused and the start toggle is a momentary switch. when you flip the ignition toggle it will kill all power to the stand alone engine harness that the fuel pump runs through. I love the old school look. The quality of these toggles when you operate them you don't see often these days anymore....I got it at Summit and yep, the price is high, but the quality is A+.

01-19-2026 First survey of my customized stand along wiring harness for the GM Vortec 4200 / ATLAS 4.2 engine swap. Keep in mind If I had kept the auto trans there would be more....I also deleted 90% of engine functions as well....only kept the cool stuff like gauge feeds, etc. At least I have a wireless throttle! enjoy the video. 01-19-2026 harness video.MOV
