Powertrain swaps are not that unusual in the Jeep world, but are typically done with domestic engines like the Buick V6 or a small block Chevrolet V8. Volvo engines are also no stranger to engine swaps – though not quite as common, the Facel Vega Facellia received the Volvo 4-cylinder both as a retrofit to make up for the shortcomings of the Pont a Mousson four-cylinder, and then as factory spec. But a Volvo 4-cylinder engine into a Jeep? That’s something new. Check out this 1964 Jeep DJ3 with a Volvo engine for sale for $3500 in Santa Rosa, CA.
