How-To Tear Down Chevy 350 Small Block Engine Motorz #63

Chris Duke starts this Motorz episode the way most real engine rebuilds actually begin: with a junkyard small block Chevy 350 and a full teardown to prep it for rebuild. It’s the first of a five-part series that follows the engine all the way through machine work, assembly, and a finished result. Watch the teardown that kicks it all off.

Every engine rebuild has to start somewhere, and it’s almost never glamorous — it starts with a junkyard find, a set of wrenches, and someone willing to take an entire engine apart piece by piece on camera so nobody watching has to learn the hard way on their own project, in their own driveway, with no one to call for help. Chris Duke does exactly that in this Motorz episode, tearing down a junkyard Chevy 350 small block to prep it for a full rebuild from the ground up. What starts as a straightforward teardown becomes a genuinely useful reference for anyone attempting the same job, complete with an on-camera correction about the very truck the engine came out of — the kind of honesty that’s rare in build content generally, where mistakes usually get quietly edited out instead of addressed head-on.

Starting With a Junkyard Engine, Not a Fresh Crate

Rather than working from a pristine, low-mileage engine pulled from a running vehicle, Chris Duke deliberately starts this series with a junkyard-sourced small block Chevy 350, the exact kind of starting point most home builders and weekend hobbyists actually work with in real life. That choice makes the teardown far more relevant to viewers planning their own rebuild, since it shows what an engine actually looks like coming apart after real-world service and completely unknown history, rather than a curated, already-clean example pulled straight from a catalog shoot. Rust, grime, and mystery history are part of the lesson here, not something edited around.

The Multi-Part Rebuild Series This Episode Kicks Off

This teardown is episode one of a five-part rebuild series that continues through the machine shop visit, the bottom end assembly, the top end assembly, and a finale showing the completed, running engine back in a vehicle. That structure means viewers aren’t just watching a single stand-alone video with no follow-through — they’re getting a full, sequential education in what a 350 small block rebuild actually requires from start to finish, with each stage documented carefully in its own dedicated episode that viewers can return to later, in order, as their own project progresses.

An On-Camera Correction, and Why It Matters

Partway through, Chris Duke pauses to correct an earlier claim about the donor vehicle, clarifying it was actually a 73-plus Chevy or GMC truck rather than the ’69 he’d originally stated on camera — a small detail in the grand scheme, but one he takes the time to fix on the record rather than letting it stand uncorrected for anyone searching for the same information later. That kind of transparency, especially in a hands-on how-to format aimed at people actually doing the work themselves, is part of why build channels like Motorz earn long-term trust from an audience that’s following along step by step in their own garage, not just watching passively.

Motorz and the DIY Engine-Building Audience

Motorz has built its reputation on exactly this kind of accessible, unglamorous, step-by-step content, aimed squarely at the DIY builder rather than a professional shop audience with a lift and a full toolset already on hand. For anyone who has ever pulled an unknown engine out of a junkyard and wondered where to even begin the process, this teardown offers a genuinely useful blueprint — proof that a full rebuild doesn’t have to start with a spotless engine to end with a running, driving one back on the road.
