If you're looking to beef up your Ford 351W, you might want to take a closer look at the Eagle Forged 4340 Steel Crank. This isn't just any crankshaft; it's built for those who really push their engines to the limit. The non-twist forging process gives it a rock-solid foundation, and those .125" fillet radiuses? They add a layer of strength that you’ll appreciate when you're pushing your rig hard. Plus, it’s got a nitrided surface and micropolished finish to keep things smooth and reduce wear over time.

Now, let's talk specs. This crank features a 2.750" main journal and a 3.500" stroke, which means you're set up for some serious power. The rod journals are 2.100", and it’s designed with internal balance in mind. That’s crucial for keeping vibrations in check, especially if you’re planning to rev it up. Just keep in mind that you’ll need to balance the crankshaft to match your specific rods and pistons, so a little prep work is involved.

  • Balance Type: Internal
  • Crankshaft Stroke: 3.500"
  • Flywheel Bolt Count: 6
  • Main Journal: 2.750"
  • Material: Forged 4340 Steel
  • Minimum Rod Length: 6.200"
  • Rod Journal Width: 1.900"
  • Rod Journal: 2.100"
  • Snout Diameter: 1.375"
  • Target Bobweight: 1900g

One thing I should mention is that this crankshaft is designed for serious applications, so if you’re planning a build that demands reliability and performance, this is a solid choice. Just remember to do your homework on fitment; while it’s pretty universal, a little research goes a long way to ensure it’ll work seamlessly with your setup.

And a quick heads-up: this product contains nickel, which California has flagged for cancer risks. So, if you’re in that neck of the woods, just keep it in mind. Overall, if you're serious about your build and want a crank that won’t let you down, the Eagle Forged 4340 is worth checking out.

Who is EAGLE?

EAGLE SPECIALTY PRODUCTS, aka EAGLE, has been at the forefront of developing top-quality engine components. The company officially started back in 1992 but has been developing their product for ten years prior.  Since the company started, it has continuously produced some of the market's best engine components and is widely used by engine builders worldwide.

Imitated But Not Duplicated

Due to the company's success, its products have been imitated by other companies even up to the part numbers. But the similarity ends only up to how they look. EAGLE uses the finest materials and has invested in the most state-of-the-art manufacturing machinery for them to create a product that would be able to take any punishment it is subjected to. It is tested to be superior to other brands and considered the best upgrade for OEM counterparts.

No To Shortcuts

The company sets the benchmark on how valves should be properly made. Using their years of experience creating rods, they have already designed over 200 different rods and 180 crankshafts. The company does not allow cost to compromise its material used, manufacturing process, and quality test. 

High-End Quality

All of Eagle's products are made up of high-quality materials. They use certified 4340 Chromoly steel. Using their own special heat treatment process, they are able to create a product that is much stronger compared to other competitors using the same raw material. 

They manufacture their rods using a 2-piece forging process that allows the rod to be stronger. This process orients the "grain" of the metal to the direction of the stress. Eagle uses a state-of-the-art Sunnen Krossgrinding system that allows them to create perfect cuts and bore consistently.
