Eagle Rotating Assembly 4" Stroke Ford 351W Mustang 1968-1996 - 16129030

If you're looking to crank up the power on your classic ride without going overboard, the Eagle Street & Strip Rotating Assembly is a solid choice. This setup is designed for those of us who enjoy a good mix of street cruising and the occasional strip run, all while running on pump gas. It's a great way to get that extra oomph without breaking the bank.

What's Inside?

  • Balanced for both street and strip use, so you don’t have to choose one over the other.
  • Displacement comes in at a sweet 408 cubic inches—plenty of muscle for your vintage Ford.
  • Mahle pistons are the real deal; they’re built to take a beating.
  • With a dome volume of -20CC, you’re looking at some serious compression.
  • The 4.000" cast crank is balanced to keep things smooth, even when you’re pushing it hard.
  • 6.250" I-beam rods are tough and lightweight, giving you the strength where you need it.
  • 3/8" ARP 8740 bolts hold everything together—no cheap stuff here.
  • Forged 4032 Mahle -20cc inverted dome 4.030" pistons ensure you get the most out of your setup.
  • Plasma-moly file-fit rings help maintain a solid seal, so you're not losing power to blow-by.
  • King Si rod and main bearings round out the package, giving you reliability you can trust.

Which Cars Fit?

  • Ford Bronco from 1979 to 1996
  • Ford Mustang from 1968 to 1970
  • Ford Thunderbird from 1977 to 1979
  • Ford Torino from 1970 to 1976

Heads Up!

One crucial thing to remember: this assembly needs to be balanced by a qualified machine shop before you hit the road. Don’t skip this step if you want to keep everything running smoothly!

So, if you’re ready to give your Ford some serious love and power, this Eagle Rotating Assembly is a fantastic way to do it. Just make sure you’ve got a good shop lined up for the balance, and you’ll be tearing up the streets and the strip in no time.

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.
