Product Details

The Eagle B42101030 is a complete balanced rotating assembly designed for Oldsmobile 455 engines, creating a high-performance 461 cubic inch stroker configuration. This Street & Strip assembly provides a cost-effective alternative to reworking original equipment parts while maintaining quality, and is recommended for naturally-aspirated, pump gas street engines.

Complete Kit Includes:

  • Eagle cast steel crankshaft with 4.250-inch stroke
  • Forged 4340 steel H-beam connecting rods with 6.735-inch length
  • 7/16-inch ARP 8740 connecting rod bolts
  • Forged flat top pistons with valve reliefs
  • Plasma moly file-fit piston rings
  • Clevite 77 main and rod bearings

This is a pre-balanced assembly, meaning the kit comes factory-balanced and ready for installation, eliminating the need for additional machine shop balancing work. Eagle Oldsmobile rotating assemblies offer an excellent balance of strength, performance, dependability and affordability, making this kit ideal for builders looking to upgrade their Olds 455 bottom end with reliable, proven components.

Easy to shop.

quick and easy

Easy to order, great price and fast shipping. Great first buying experience.

Chat was very helpful

No Comment, all went well with order

Always great service.

Came on fast. Recommend having specs of product on site - such as length. Had to order a second one.

Sender arms were long enough that I could bend arms to match oem.

Ordered two of the same windshield wipers, and they shipped separately.. one was packed very nicely in an oversized box... the other was wrapped in a plastic mailer and arrived with the clips inside crushed
