Product Details

ACL Bearings 8B745H-010 Race Series Connecting Rod Bearings deliver competition-proven performance for Small Block Chevy 283 and 327 ci V8 engines with small journal crankshafts. Engineered with .010" undersize dimensions, these bearings are designed for reground crankshafts and high-performance racing applications.

Advanced Tri-Metal Construction:

  • High-strength overlay plate with reduced thickness for improved fatigue resistance
  • Hardened steel backing provides superior support and bearing retention in the housing
  • Tri-metal composition featuring lead, tin, copper, and nickel for exceptional strength and seizure resistance
  • No flash plating on bearing backs to maximize heat transfer and improve grip

Race-Engineered Features:

  • Micron-tolerance machining ensures consistent wall thickness and proper crush
  • Increased eccentricity compensates for bore distortion at high RPM
  • Assists in formation of hydrodynamic oil film for superior lubrication
  • Enlarged ID chamfers accommodate large fillet radius performance crankshafts
  • 2.000" journal diameter (small journal) for 283 and 327 ci applications

Application: Small Block Chevy 283, 327 ci V8 engines with small journal crankshaft (.010" undersize). Part of ACL's Race Series lineup proven in NASCAR, IHRA, NHRA competitions, and championship-winning engines from drag strips to Bonneville.

Precision-manufactured to exacting tolerances for reliable fit and consistent clearances in high-RPM racing conditions.

Great pricing on hard to find products. Fast processing and shipping.

Incredibly low prices and fast shipping. I bought shocks and struts for my truck and saved more than 35% over what my local parts store wanted!!! I made the mistake of not setting up my account before placing my order so I didn't get confirmation right away, but one quick phone call fixed that. Great customer service.

Good Seller, very quick shipping and excellent transaction.

I used Autoplicity for the first time less than a week ago. I ordered some 5' fog light covers. They arrived in a short time, Just what I thought they would be, and 100% satisfied with the product and fast shipping they provided.

Autoplicity.com had the lowest price available for what I was looking for. Within 24 hrs I had an order confirmation and tracking information. I have no complaints, and will likely do business with them again.
