Diagnosing a Poor Running Chevy 350 @AutoRestoMod

Uploaded August 2025 | Updated September 2026, 8 hours ago

We thought it was just a carburetor issue… but our friend’s Chevy 350 had a much bigger problem. While troubleshooting, we found dead cylinders on #8 and #5, and things got interesting fast. In this episode, we dive into how we discovered the real cause, what symptoms to look for when diagnosing a small-block Chevy misfire, and why sometimes the carburetor gets blamed when it’s actually something deeper in the engine.

Whether you’re working on a Chevrolet small block, restoring a classic, or just curious about engine diagnostics, this video will walk you through the process step-by-step. From compression testing to spark checks, we cover the key reasons a cylinder might go dead — and how to fix it before more damage is done.

How to Polish Oxidized Aluminum Wheels (On the Car!)

$Cheap tricks for a Clean Wiring Install on Your Classic Car Last week we neatened up the charging system and set it up for our CVF Racing serpentine belt system. This week we deal with the leftovers — the wiring somebody else left behind in this engine bay — and turn a tangle of mismatched harness into something that looks like it belongs. This isnt a jot-and-tittle, every-wire walkthrough. Its the tips and tricks that make the difference: start with a plan, drape and route your wires toward where they actually need to land, and decide up front where things like corrugated loom belong (and where they dont). We work through the American Autowire engine harness, the VSS leads for a future speed-sensor setup, and the runs out to the water temperature and oil pressure senders — leaving access for whatever Kylie may want to add down the road. Along the way we run into the usual first vexation of any classic-car project: figuring out what the last fellow cobbled together and why. In this case its the wire feeding the start circuit at the starter solenoid — a small thing that tells you everything about how the car was wired before it got here. What came in as a fifteen-minute, four-bolt transmission job on this 67 Mustang turned into a tour through every system — suspension, transmission, engine, and interior. Kylies ready to drive it, and so are we. It just takes a few more careful tweaks like this one. Our thanks to National Parts Depot for helping keep these classic Fords on the road.
