3800 Wiki is a community-focused reference site dedicated to collecting, organizing, and preserving practical information about the 3800 engine. Created to bring knowledge together from scattered and sometimes disappearing 3800-focused forums, the wiki aims to make useful technical guidance easier to find and maintain in one place. Its content covers engine specifications and internals, including the engine block, fasteners, torque specifications, and camshafts.

It also provides material on performance modifications, ignition and fueling improvements, supercharging and turbocharging, transmission options, and tuning with factory PCMs or aftermarket engine control units. Additional resources include aftermarket part numbers, a record book, YouTube features, useful links, and 3800-focused forums. The site is intended as a collaborative knowledge base: visitors can register, log in, and contribute edits or suggest topics for documentation.

Its editors acknowledge that the wiki is still developing and that some pages may be incomplete. The project is presented as an independent resource without ads or sponsors, and its content is licensed under Creative Commons Attribution-ShareAlike 4. 0 International unless otherwise noted
