LL8 / Vortec 4200 Builder Resources

This curated resource hub collects the practical references behind the site, with extra emphasis on LL8 / Vortec 4200 diagnostics, Atlas Bot support material, and builder-oriented places to keep reading.

Some links here point deeper into ShoddyTechGarage LLC itself, while others point to outside resources worth keeping close when you are comparing diagnostics notes, swap research, teardown references, and project context.
