GMC Yukon Engines by Year

GMC's full-size Yukon arrived for 1992, the Tahoe's twin. The longer Yukon XL replaced the GMC Suburban for 2000, and the Denali added its own engines. Three-quarter-ton XL 2500 engines and the 2008–2013 hybrid are included; hybrid ratings are for engine and motors combined.

Which engine is this?

• 1992–2026: the 8th character of the VIN is the engine code.

Where the engine code is stamped

• Chevrolet small-block V8 (283, 305, 307, 327, 350 gas) and 4.3L 90-degree V6: Engine suffix/assembly code stamped on the machined pad on the front of the passenger-side (right) block deck, just ahead of the right cylinder head; the partial VIN is on the same pad. GM lists an alternate spot on the vertical block surface behind the oil filter.

Engines get swapped. The VIN tells you what the car left the factory with; the stamp on the block tells you what is in it now.

Working on one of these engines?

• Engine displacement from bore and stroke
• Static and dynamic compression ratio
• Which camshaft for your build
• What size carburetor
• Horsepower to torque at any RPM
• Torque converter stall speed
