Selecting the right crankshaft is crucial for building a reliable and high-performance Ford 351W engine. Here's a buying guide to help you make the best decision:
1. Material and Construction:
- Consider the material and construction of the crankshaft. Cast iron crankshafts are durable and cost-effective, making them suitable for most applications. For high-performance builds, forged steel crankshafts offer superior strength and reliability.
2. Stroke:
- Determine the desired stroke for your engine build. The 351W engine comes with a standard stroke of 3.500 inches, but aftermarket crankshafts may offer different stroke options for increased displacement and performance.
3. Balance Type:
- Choose between externally balanced and internally balanced crankshafts. Externally balanced crankshafts require additional balancing weights on the flywheel or flexplate, while internally balanced crankshafts do not. Ensure compatibility with your engine's balancing requirements.
4. Main Journal Size:
- Pay attention to the main journal size of the crankshaft. The 351W engine typically uses a 2.749-inch main journal size, but aftermarket crankshafts may offer different journal sizes. Ensure compatibility with your engine block and bearings.
5. Brand Reputation:
- Purchase your crankshaft from a reputable manufacturer known for quality and reliability. Research customer reviews, dyno testing results, and track records to ensure you're getting a high-quality crankshaft that delivers on its promises.
6. Compatibility:
- Ensure compatibility with other components of your engine build, including connecting rods, pistons, bearings, and engine block. Choose a crankshaft that matches the specifications and requirements of your desired engine configuration and performance goals.
7. Budget Considerations:
- Establish a budget for your crankshaft purchase and consider the features and specifications you need within that budget. Compare prices from different suppliers to find the best value for your money without compromising on quality.
By considering these factors and following this buying guide, you can confidently select the right crankshaft for your Ford 351W engine build, ensuring reliable performance and durability.
