The LS Rebuild Blueprint. Manual 01, the flagship.
Six modules covering the LS family end-to-end — annotated cross-section blueprint, tool checklists per phase, torque sequences & angle specs, do-this-not-that callouts, the GM ↔ ACDelco ↔ Fel-Pro ↔ Mahle parts cheat sheet, and the stage-by-stage build sheet.
One PDF. One-time price. One wrencher’s bench. The cheat-sheet that should have shipped with the engine in the first place.

LS 5.3 Builder’s Guide & Project Workbook
The Cozart Garage LS 5.3 Builder’s Guide is currently being rebuilt into a cleaner V2.0 Illustrated Builder Edition. This update will include printable worksheets, build logs, technical diagrams, workflow checklists, and an LC9 reference appendix for garage builders who want to plan, document, and finish their project the right way. Final V2.0 release coming soon.

Four chapters a shop-floor wrencher opens first.
The full manual is six modules — these four are the ones every reviewer opens first because they answer the question you actually have at the bench, not the one the forums argue about.
Annotated LS V8 cross-section blueprint
Every measurement on the block, in the lifter valley, and through the oil galley — pulled from the engine the manual was written on, not paraphrased from a manual nobody owned.
Tool checklists per phase
3/8 and 1/2 drive wrenches, sockets from 10mm to 19mm, and the specialty tools (harmonic balancer puller, ring compressor, piston ring installer) — listed per phase so you don’t pull a tray full of stuff you won’t use.
Torque sequences & angle specs
Cylinder head, intake, oil pan, mains, rods — three-stage torque values in ft-lbs and NM, the matching angle sequences, and a numbered LS-head callout you can mark with a Sharpie.
Do-this-not-that callouts
The mistakes you’ll pay for if nobody warned you — cheat-bar extension, knuckle-on-radiator, dry-gasket, wrong-torque-angle. Each callout shows the wrong posture next to the right one.
One-time. $19. Instant download.
Buy once, re-download from your account for 30 days, and forward the receipt link to a mate on the lift. Stripe-hosted checkout — no marketplace middleman.
Three promises this manual keeps.
Same as on the about page — because the only reason a trust strip changes is when a promise stopped being true, and these three still hold.
PDF, one-time, instant download
No DRM, no subscription, no marketplace middleman. After checkout the PDF link lands in your inbox within a minute, plus your account holds a re-download for 30 days.
Every spec from a real build sheet
Torque values, part numbers, and tool lists were copied off the build sheet of the engine the manual was written on. The first build, the second build, the third.
Indie pricing on purpose
A one-time price that fits the hobby sweet spot — the kind of price a weekend wrencher can pay out of the parts budget without blinking, and the kind of margin that ships an errata update for free for life.
