Full Build: Duramax Swapped Classic Squarebody - 1987 Chevy 1500

We're taking an '87 Chevy 1500 and giving it a serious upgrade into Project Nightrain. We're swapping out the old gas V8 for a powerful Duramax diesel engine paired with an Allison transmission, turning this classic two-wheel drive, regular cab short bed truck into a high-powered diesel beast. We've sent off the harness to be transformed into a stand-alone setup, and they're even tweaking the PCM for some extra oomph. The truck's got some mileage, but the real excitement lies in making room for the big diesel, modifying the exhaust system, and tackling that school-bus-sized transmission. Of course, we didn't forget style—our Chevy will sport a fresh cowl hood to accommodate all that power under the newly painted roof, blending that midnight blue perfectly.
