Shop-built LS rebuild manuals.
And the gear to match.
Every page photographed and written from a real engine stand — full-color teardown shots, torque specs pulled off the actual build sheet, and the do-this-not-that notes you only get from turning the wrenches yourself.
Written so you can use it with one hand on the ratchet.
Indie PDFs in the hobby sweet spot. No upsells, no DRM, no forum threads — the kind of reference a wrencher actually keeps taped to the lift.
Written from the shop floor
Each photo and every spec was pulled from a real pull-down and re-assembly — not paraphrased from a manual nobody owned.
Cheat sheets over chapters
You came here to finish the build. The guide is built to be referenced mid-torque, not read on a couch.
Priced for the hobby market
Indie sweet spot, $9.99 – $19.99. No upsells, no DRM, every build of the manual is yours forever.
Six modules. One manual you can actually use.
Built to be referenced at the workbench, not read on a couch. Every spec was pulled from a real build; every chart was drawn in the shop.

LSx swap decision matrix
LS1 → LS9: bore, stroke, intake pattern, and which one loves boost.
One family of engines. A whole manual library to match.
The flagship LS manual is the front door. Every engine in the LSx family gets its own edition — same lab-bench format, every step referenced to the actual platform.

After the LS caps come the platform rebuilds.
Swap-specific books cover the chassis end of the equation — engine mounts, fuel return-routing, oil-pan baffles for low clearance pans, harness pinout tables.
The wrencher's questions.
What the manual is, how the brand grows, and where the apparel line lives in the plan. Drop a note at cozart-garage@polsia.app if your question isn't here.
Manuals first. Apparel next. Decals always.
Every download pulls one more wrencher closer to the merch table — tees, hoodies, shop caps, decals. Same audience, same blueprint that turned an answer thread into a brand name you already trust.
