2000 International 3800 Partial Conversion

If you’re looking for a solid, full-size school bus conversion project with all the hard work started and a rock-solid drivetrain, this is it.

This is a 2000 International 3800 with the legendary 7.3L T444E diesel engine (same family as the Ford Powerstroke) paired with an Allison AT545 automatic transmission. Odometer shows 155,000 miles, but we’ve invested over $15,000 into a professional engine rebuild ( I have receipts) — so mechanically, it’s ready to go anywhere. Runs smooth and strong.

✅ Conversion Work Already Completed

• Completely gutted interior – ready for your layout

• New subfloors installed for a solid build base

• Full waterproofing to protect against leaks and moisture

• Two 2’x2′ low-profile glass skylights with manual crank openers – adds tons of natural light and ventilation

• Solid chassis and body – no major rust issues typical of northern buses

🛠 Mechanical Highlights

• 7.3L International T444E diesel – legendary reliability

• Allison AT545 4-speed automatic transmission

• Recent engine rebuild – extremely low miles since

• Well-maintained, always starts and runs great

📍 Location: Central Texas – clean title in hand

We’re expecting our first child and simply don’t have the time to finish the build. This bus is perfect for someone who wants a blank canvas with the expensive work already done — just bring your design ideas and finish the conversion your way.

💰 Asking Price: $17,500 – open to reasonable offers from serious buyers.
