About LSSwapBible

LSSwapBible is a reference for swapping GM LS and LT engines into anything: engines, donor vehicles, parts lists with real prices, cams, calculators and answers.

Everything here comes from a database built from manufacturer documentation, vendor catalogs, published guides and aggregated owner reports — 107 sources and counting. Each page lists its sources so you can check our work.

We are independent: not affiliated with GM, Chevrolet Performance or any parts vendor.
