Product Details

The Eagle B15404E040 is a complete balanced rotating assembly designed for building a high-performance 383 cubic inch Small Block Chevy stroker engine. This kit is engineered for .040" overbored blocks and includes all the essential internal components needed to transform your SBC into a torque-rich 383 stroker.

Kit Includes:

  • 4340 forged steel crankshaft with 3.750" stroke
  • ESP forged 5.7" H-beam connecting rods
  • Forged flat top pistons (.040" oversize) with rings, pins, and locks
  • Performance main and rod bearings
  • Factory balanced assembly for smooth operation

Key Specifications:

  • Displacement: 383 cubic inches
  • Bore: 4.040" (standard 4.000" + .040" overbore)
  • Stroke: 3.750"
  • Rod Length: 5.700"
  • Compression Height: Typically 1.560" (for flat top configuration)
  • Balance: Internally balanced (50 oz)

This rotating assembly is ideal for street performance, bracket racing, and street/strip applications. The 383 stroker combination provides excellent low-end torque and strong mid-range power, making it one of the most popular SBC performance builds. Eagle's precision machining and quality materials ensure reliability and durability for demanding applications.

Note: Designed for use with standard small block Chevy blocks bored .040" over. Professional installation and proper clearancing recommended.

they had what I needed in stock and at the right price.

fast delivery item as described

Fast and easy

Hope it gets here in seven days

Easy

I am very satisfied with the order/delivery/and overall quality of the product. I emailed a small problem with a broken plastic end cap on the handle end. I used the email about the shipment from autoplicity to reply about the problem. I have also found a problem with a missing washer that goes on the support tube prior to installing the step assembly. Couldn't find it in the package. I haven't received a reply. It is a small problem.

Easy to use site with the parts that I need at good prices.
