Chevy 292 Inline-6 Firing Order and Cylinder Numbering
Chevy 292 Inline-6 Firing Order and Cylinder Numbering: 1-5-3-6-2-4, cylinder numbering, compression-TDC setup.
The 1971 Chevrolet 292 Inline-Six firing order is 1-5-3-6-2-4. Cylinders 1-2-3-4-5-6 run from the radiator/front toward the transmission.
The 1971 Chevrolet 292 Inline-Six firing order is 1-5-3-6-2-4. Cylinders 1-2-3-4-5-6 run from the radiator/front toward the transmission.
The exact specification is anchored to Chevrolet's 1971 truck heritage data for the 292 inline-six. Other years and industrial conversions require their own distributor, timing and emissions procedures.
Chevrolet's 1971 truck specification groups the 250 and 292 inline-sixes under firing order 1-5-3-6-2-4, while their dimensions and service parts remain distinct.

How to use this specification correctly
- 01
Confirm engine identity from the VIN, emissions label and casting information.
- 02
Bring cylinder 1 to compression TDC before disturbing distributor routing.
- 03
Label and trace one wire, coil or injector circuit at a time, then verify with misfire data.
Chevrolet's 1971 292 specification
Chevrolet's truck information kit identifies the High Torque 292 as an inline, valve-in-head six and lists 1-5-3-6-2-4 for the 250/292 six-cylinder group. The cylinders run 1 through 6 from the front of the engine toward the transmission.
The shared order does not make a 250 and 292 interchangeable. Chevrolet's same table shows different stroke, rod length, output and other specifications. Identify the taller 292 installation and its component numbers before ordering a distributor, manifold, mounts or internal parts.
Finding number 1 without relying on a cap photo
If the existing wire layout is trustworthy, label every lead and mark the rotor before disturbing it. If it is not, bring the front cylinder to top dead center on its compression stroke. Both valves should be closed and compression should be evident; a timing mark alone can also represent exhaust TDC.
With the distributor correctly engaged, the cap tower above the rotor becomes the number 1 reference. Route the remaining leads 1-5-3-6-2-4 in the verified distributor direction. Preserve separators and clearance from the exhaust manifold.
What firing order cannot tell you
The sequence cannot select initial timing, point gap, dwell, vacuum advance or governor settings. Chevrolet offered the 292 across truck calibrations, and those surrounding specifications depend on year, emissions package, transmission and distributor identity.
After restoring correct routing, set dwell where applicable before timing because changing point gap changes ignition timing. If the engine still backfires or lacks power, verify compression-TDC indexing and valve timing instead of hiding an error by rotating the distributor.

Chevrolet 1971 Chevrolet 292 Inline-Six specifications can change by model year, engine, platform, wheel, and installed component. Confirm the VIN or engine identity, part numbers, fastener condition, and the current manufacturer instructions before service.
Chevy 292 Inline-6 Firing Order and Cylinder Numbering FAQs
What is the Chevy 292 inline-six firing order?+
The 1971 Chevrolet truck specification lists 1-5-3-6-2-4.
Where is cylinder 1 on a Chevy 292?+
It is the front cylinder nearest the radiator; numbering continues toward the transmission.
Do Chevy 250 and 292 engines share a firing order?+
Yes in the cited 1971 data, but their dimensions, parts and other service specifications are not interchangeable.
Can a timing-mark check alone prove number 1 is ready for distributor installation?+
No. Verify compression TDC because the crank mark can also align at number 1 exhaust TDC.
