Hey there, gearheads! If you're looking to kick your engine's performance up a notch without breaking the bank, check out the Eagle Street & Strip Rotating Assembly. This isn't just some cookie-cutter kit; Eagle really puts thought into sourcing quality components that won’t leave your wallet empty. Perfect for naturally-aspirated, pump gas street engines, this assembly is designed for those who want reliable power on the road.

Now, let’s get into the nitty-gritty. This assembly features a 4.250" cast crank paired with 6.385" I-Beam rods. Those ARP 8740 bolts? They’re tough as nails, ensuring everything stays put under pressure. You’ve got forged 4032 Mahle pistons with an 18cc dome, which means you're getting solid compression without sacrificing durability. Plus, the plasma-moly file-fit rings and King SI rod/main bearings are included, so you’re set up for smooth operation right out of the box.

Key Specs:

  • Assembly Balanced: Yes
  • Balance Type: External
  • Connecting Rod Bolt Diameter: 7/16"
  • Connecting Rod Length: 6.385"
  • Crankshaft Stroke: 4.250"

Just a heads up, you might need to do a bit of minor clearancing on the block to get everything to fit just right, but that’s pretty standard with performance upgrades. This assembly is designed to work seamlessly with your Chevy Big Block, so you can count on it to deliver when you hit the gas.

Important Notes:

Universal Fitment: While this assembly is designed to fit a range of applications, it’s always a good idea to double-check compatibility with your specific setup. Do your homework to ensure you're getting the right fit for your ride.

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.
