Why You Should Buy Parts from Diesel Pro Power to Build a Detroit Diesel 8V71 Longblock
Rebuilding a Detroit Diesel 8V71 longblock is no small task. This legendary two-stroke V8 engine, part of the famous Detroit Diesel Series 71 family, powered vessels, industrial machines, buses, and trucks for decades. Known for its unmistakable sound and rugged reliability, the 8V71 remains one of the most rebuilt engines in diesel history. But when you take on a rebuild of this scale, success depends on one critical choice — where you buy your parts.
For professionals and enthusiasts alike, Diesel Pro Power has become the go-to source for Detroit Diesel components. Here’s why buying your 8V71 rebuild parts from Diesel Pro Power ensures your longblock comes together with precision, performance, and peace of mind.
The Detroit Diesel 8V71: Built to Last, Worth Rebuilding
The Detroit Diesel 8V71 features eight cylinders arranged in a compact 90-degree V configuration, with each cylinder displacing 71 cubic inches — totaling 568 cubic inches (about 9.3 liters). It’s a two-stroke diesel that uses a Roots-style blower for scavenging air and delivering that iconic high-pitched whine that Detroit enthusiasts recognize instantly.
Many of these engines have served faithfully for decades in marine, industrial, and transport applications. But even the most durable engines reach a point where they need a fresh start — a complete longblock rebuild. Rebuilding an 8V71 correctly means renewing the heart of the engine with new pistons, liners, bearings, connecting rods, crankshaft, camshaft, and cylinder heads.
That’s where Diesel Pro Power comes in.

3. Everything You Need, All in One Place
One of the most frustrating parts of a rebuild is sourcing components from multiple suppliers. Cylinder liners from one place, bearings from another, gaskets from yet another — and hoping everything fits together.

Their comprehensive approach includes:
-
Pistons and liners

Each part is designed for proper integration, ensuring a smooth assembly process and consistent engine performance once your longblock is complete.
4. Expertise That Saves You Time
The 8V71’s two-stroke architecture can be challenging, even for experienced diesel mechanics. Its blower system, unit injectors, and port timing differ significantly from modern four-stroke engines.
