The DSS Racing 1-3406-4030B DSS FX Piston Set 306 Rod SBF 13cc Dish Top TFS Twisted Wedge is a high-performance piston set designed for Small Block Ford (SBF) engines. Here are some pros and cons to consider before making a purchase.

1. High-quality materials: The pistons are made from forged 2618 alloy, which provides excellent strength and durability.

2. Twisted wedge design: The piston's twisted wedge design reduces friction and helps prevent detonation, leading to improved performance and reliability.

3. Dish top design: The dish top design improves compression and helps increase horsepower.

4. 306-rod length: The 306-rod length is suitable for many SBF applications, providing a good balance between performance and reliability.

5. Suitable for high-compression applications: The 13cc dish top design makes this piston set suitable for high-compression applications, which can lead to increased horsepower.

1. Expensive: Compared to stock pistons, these high-performance pistons are more expensive.

2. May require other modifications: To fully realize the potential of these pistons, other modifications such as a high-performance camshaft, intake, and exhaust may be required.

3. Not suitable for all SBF applications: While the 306-rod length is suitable for many SBF applications, it may not be suitable for all engines, particularly those with low-compression ratios or low rpm applications.

4. May require professional installation: Installing high-performance pistons can be a complex process and may require professional installation to ensure proper fitment and performance.

The DSS Racing 1-3406-4030B DSS FX Piston Set 306 Rod SBF 13cc Dish Top TFS Twisted Wedge is a high-quality, high-performance piston set that can provide significant gains in horsepower and reliability for SBF engines. However, it is more expensive than stock pistons, and may require other modifications to fully realize its potential. If you are looking to build a high-performance SBF engine and are willing to invest in high-quality components, this piston set could be a good choice. If you are on a budget or have a lower-compression SBF engine, there may be less expensive alternatives available. Ultimately, it is important to carefully consider your engine's specific requirements and budget before making a purchase.

Details:

You would have to do the math see if that is feasible.They a .927 pin and thin 1.2mm X 3mm ring pack which are still like new. I am sure the rings would seal just fine on a newly honed cylinder. I see another set listed with the same part number stating they would make a 393W but am unsure if that is accurate. This is a set of DSS FX pistons for inline or Twisted Wedge heads.

We ran this engine on the Dino and ended up swapping to a striker setup make more HP.
