Product Details

The Manley 14054R-8 H-Beam connecting rods are engineered for high-performance Small Block Chevrolet applications requiring strength and reliability at elevated RPM levels. These premium connecting rods are forged from aircraft-quality 4340 steel alloy that has been vacuum degassed for optimal material purity and strength characteristics.

Construction and Manufacturing:

  • Forged from 4340 steel alloy with compact uniform-grain structure for maximum strength
  • Fully machined to achieve the lightest possible weight while maintaining structural integrity
  • Shot peened after machining to military specifications for enhanced fatigue resistance
  • 100% magnafluxed to detect any surface or subsurface defects
  • Stress relieved to minimize internal stresses and improve durability

Precision Engineering:

  • 6.000 inch center-to-center length (+0.300 inch longer than stock)
  • 2.100 inch crankshaft journal size (large journal)
  • 0.9281 inch piston pin bore with bronze alloy bushing for full-floating wrist pins
  • Wrist pin and big end bores honed to +/- 0.0002 inch tolerance
  • Weight matched to within +/- 1.5 grams for optimal balance
  • 640 grams advertised weight per rod

Premium Hardware:

  • Includes ARP 2000 cap screws (7/16 inch) for superior clamping force and reliability
  • Upgraded from standard ARP 8740 bolts for racing applications

This set includes 8 connecting rods and is designed for racing use. Note that custom pistons are required when using longer-than-stock connecting rods. These rods are NHRA legal for Oldsmobile 307ci, 350ci, and 403ci Stock and Super Stock classes.

Lightning fast service! Good prices.

Received my package today. Shipping was fast and it was about the best price I could find for my Cam. I'll buy from them again.

Thanks for the quick and easy experience.

I'll start off saying that Autoplicity's prices are unbeatable...but, I placed my order on a Saturday night (which I know is the weekend)on a in stock part and it took them till the following Thursday to ship it out. I use my truck to make a living and was hoping to get it a little quicker, but now I'm down another 3-4 days till the part gets here. Also, I sent a e-mail on Tuesday evening regaurding my order and never got a response.

Autoplicity, was very easy to use, very fast, and an enjoyable experience. I would recommend to my closest friends!!
