If you're diving into the world of naturally-aspirated racing, you might want to check out the Eagle Pro Street Rotating Assemblies. These bad boys are built for performance and reliability, making them a solid choice for anyone looking to crank up the power in their ride.
Let's talk specs. This assembly is designed for a displacement of 410 cubic inches, which gives you plenty of grunt when you hit the gas. The pistons are Mahle, specifically crafted with a -20CC dome volume, so you know they're ready to handle the heat. And speaking of heat, the 4.000" forged 4340 steel crank is tough enough to take whatever you throw at it, while the 6.250" 4340 I-beam rods keep everything in check.
Now, I can't stress enough how important the little details are. The 7/16" ARP 8740 bolts ensure everything stays snug, and the forged 4032 Mahle pistons with -20cc inverted dome are designed to give you that extra edge. Plus, those plasma-moly file-fit rings? They’re there to help your engine seal up tight and run smoothly. And let’s not forget about the King XP rod and main bearings, which are known for their durability and performance under pressure.
As for fitment, these assemblies are compatible with a range of classic Fords, including the Bronco from '79 to '96, the Mustang from '68 to '70, the Thunderbird from '77 to '79, and the Torino from '70 to '76. So, if you’ve got one of these beauties sitting in your garage, you’re in luck.
Just a heads up, though—make sure you get this assembly balanced by a qualified machine shop before you hit the track. It’s a crucial step that can’t be overlooked if you want to keep things running smoothly.
In short, the Eagle Pro Street Rotating Assembly is a fantastic upgrade for your Ford if you're serious about racing. It’s built tough, designed for performance, and ready to help you unleash some serious horsepower.

It is tested to be superior to other brands and considered the best upgrade for OEM counterparts.
No To ShortcutsThe 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 QualityAll 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.
