Datsun 510 Performance: Achieving 180 Hp with Custom Built Short Block for $3,500

The Datsun 510 is a classic car that has garnered a loyal following among automotive enthusiasts. With its lightweight design and rear-wheel-drive layout, it’s a perfect canvas for performance upgrades. This article will explore how to achieve 180 horsepower with a custom-built short block for around $3,500.

Understanding the Datsun 510

The Datsun 510, produced from 1968 to 1973, is known for its sporty handling and simplicity. It features a four-door sedan body style and is powered by a variety of inline-four engines. Over the years, enthusiasts have discovered ways to enhance its performance significantly.

Why Upgrade the Short Block?

The short block is the heart of the engine. It includes the engine block, pistons, crankshaft, and connecting rods. Upgrading the short block can lead to substantial gains in horsepower and torque, making it an essential step for those looking to maximize the performance of their Datsun 510.

Components Needed for the Custom Built Short Block

Engine block (preferably from a later model Datsun)
Pistons (high-compression, forged preferred)
Crankshaft (lightweight, performance-oriented)
Connecting rods (stronger aftermarket options)
Oil pump (high-volume for better lubrication)
Gaskets and seals (quality aftermarket parts)

Building the Short Block

Building a short block requires precision and knowledge of engine assembly. Here’s a step-by-step guide to help you through the process.

Step 1: Selecting the Engine Block

Start with a solid engine block. Look for a Datsun L-series engine block that is free from cracks and damage. A block from a later model will typically provide better performance due to advancements in design.

Step 2: Choosing the Right Pistons

Select high-compression pistons to increase the engine’s efficiency and power output. Forged pistons are recommended for their strength and durability under high-stress conditions.

Step 3: Crankshaft and Connecting Rods

A lightweight crankshaft will reduce rotational mass, allowing the engine to rev more freely. Pair it with stronger aftermarket connecting rods to handle increased power without bending or breaking.

Step 4: Assembly

Carefully assemble the short block, ensuring all components are properly torqued to specifications. Use quality gaskets and seals to prevent leaks. Consider using assembly lube on critical components to ensure proper lubrication during initial startup.

Budget Breakdown

Here’s a rough budget breakdown for building a custom short block for the Datsun 510:

Engine block: $500
Pistons: $600
Crankshaft: $700
Connecting rods: $400
Oil pump: $200
Gaskets and seals: $100
Labor (if applicable): $1,000

Total estimated cost: $3,500

Expected Performance Gains

With the custom-built short block, you can expect to achieve around 180 horsepower. This significant increase in power can transform the driving experience of the Datsun 510, making it a more thrilling and engaging vehicle to drive.

Additional Modifications for Enhanced Performance

To maximize the performance of your Datsun 510, consider additional modifications alongside the short block upgrade:

Upgraded carburetors or fuel injection systems for better air/fuel mixture
Performance camshaft for improved valve timing
High-performance exhaust system to reduce back pressure
Upgraded ignition system for better spark and efficiency
Suspension upgrades to improve handling and stability

Conclusion

Building a custom short block for your Datsun 510 is an exciting project that can yield impressive performance gains. With a budget of around $3,500, you can achieve 180 horsepower and significantly enhance your driving experience. Whether you’re a seasoned mechanic or a novice enthusiast, this upgrade can bring new life to a classic car.
