About the shop

One wrencher. One shop floor. One manual at a time.

Cozart Garage is what happens when the answer-thread habit meets an actual engine stand. The manuals are the receipts — every photo and every torque value pulled from a real pull-down in the same shop where the builds happen.

Stripped of the marketplace gloss, the affiliate links, and the upsell drip. Just a wrencher, a walk-in customer, and the cheat-sheet that should have shipped with the engine in the first place.

Cozart Garage — LS rebuild specialist working on a truck on the shop floor
The story

From forum-thread habit to published manual.

Four beats that explain how an answer-thread habit turned into the customer base of a one-wrencher publishing imprint — and why the manuals look the way they do.

  1. 01

    How the manuals started

    The first manual was the one I'd been asking for in every LS forum thread — the kind that showed the actual torque value, on the actual bolt, from the actual build sheet. When nobody shipped it, I pulled a transmission on a weekend and started writing. That was Manual 01. The rest of the LS family is the long-game plan, one wrench session at a time.

  2. 02

    Why LS

    LS is the swiss-army knife of the hot-rod bay — affordable, plentiful, well-documented at the engineering level, and forgiving enough that a weekend wrencher can finish a build without trashing the engine. The manuals focus on LS because that's what's parked on the engine stand. Other engine families stay on the roadmap once the LS shelf is full.

  3. 03

    What 'shop-floor' means here

    Every photo and every torque value in a Cozart Garage manual was pulled from a real pull-down and reassembly. Not paraphrased from a manual nobody owned, not lifted from a third-party forum post — tightened or loosened on the bench during the build the photographs came from. That's the cheat-sheet of mistakes you've already paid for, written down so the next wrencher doesn't repeat them.

    The shop today

    One wrencher, one workspace, one published manual at a time. Stripe checkout, instant download link in your inbox, 30-day refund if it isn't what you expected. The roadmap is the LSx family end-to-end (LS1 onto LS9, including the truck variants), then platform-specific swap books for the chassis that take an LS happily.

The workbench

How the manuals get made.

The same recipe every time: a real build, a real teardown, a real camera on the workbench. Then a week of writing so the next guy doesn't have to repeat the same mistakes.

From the engine stand to a 120-page PDF.

  • Pull-down: the engine goes onto the stand; every fastener gets photographed, torque-stamped, and bagged in order.
  • Build sheet: GM part numbers, ACDelco, Fel-Pro, and Mahle cross-references get put into the cheat sheet side-by-side.
  • Reassembly: the engine goes back together with the manual open, every torque sequence typed and timed — first time, second time, third time.
  • Publish: full-color teardown photos, live torque specs, do-this-not-that callouts, and the part-number cheat sheet ship as the next manual in the series.
The receipts

Three promises the manuals keep.

The same three things we've told every first-time customer since Manual 01. They hold up because they're true, not because they're on the landing page.

Direct contact, no middleman

A real wrench-turner reads the inbox — no ticket queue, no support bot. Drop a line for a preview chapter, a torque-spec sanity check on your build, or a fleet-order discount.

Every spec from a real build sheet

Torque values, part numbers, and tool lists are copied off the build sheet of the engine the manual was written on — not paraphrased from a manual nobody owned.

Indie pricing on purpose

$9–$24 keeps the manuals in 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 lets every errata update ship free for life.
