The exact lineup has evolved over the van’s generations, with diesel becoming more common in recent years for higher-mileage or heavy-load use.
Engine options
The following engine options reflect the current and recent configurations most commonly found on the Express 3500. Availability can vary by year, body style, and market.

Older and alternative powertrains
Earlier generations of the Express 3500 sometimes offered an 8.1L V8 gasoline engine in certain markets or configurations. This big-block option was largely phased out as GM updated the lineup with smaller-displacement V8s and the Duramax diesel, and it is rarely seen on new or recent used examples today.

For most buyers shopping today, the standard choices tend to be the 4.3L, 5.3L, and 6.0L gas engines, with the 2.8L Duramax diesel available in select configurations and regions. Always verify the exact engine on a specific vehicle’s VIN.
