Product Details

The Manley 290030R is a complete Small Block Chevy 383 cubic inch rotating assembly designed to maximize displacement and power output from the popular SBC platform. Built around a 3.750-inch stroke and 4.030-inch bore, this stroker kit delivers the proven 383 CID combination that has been a go-to choice for street performance and race engine builders for decades.

Key Features:

  • Manley 4340 forged steel crankshaft — heat treated, stress relieved, shot peened, and nitrided for maximum strength and durability
  • 3.750-inch stroke on 350 main journals for direct SBC block compatibility
  • 4.030-inch bore pistons matched to common .030-over cylinder bore specifications
  • Manley forged connecting rods with premium ARP cap screws for high-horsepower reliability
  • Manley forged aluminum pistons precision-matched to the stroke and compression target
  • Complete kit precision internally balanced by Manley in-house for a ready-to-install assembly
  • All rotating components are 100% Magna-Fluxed for quality assurance

The Manley 290030R rotating assembly is engineered for builders who demand OEM-quality fit with race-proven performance. Whether used in a dedicated street machine or a high-output race application, this kit provides a reliable foundation for a powerful 383 cubic inch Small Block Chevy build.

Fast shipping cheapest I could find, easy to deal with, great product

Ordered the Auto Ventshade Ventvisor Deflector 4 pc. (Model 94856) for my 2000 Toyota Camry XLE. Was easy to install with no tools, just use the included strong double sided adhesive tape. Instructions that came with it could've been more detailed on where exactly to install the ventshade as I had to remove them tediously, realizing I had to put them a little higher. Also, there seems to be an unsightly gap between the front and back windows. Works as designed. Satisfied with product. Fast shipping by Autoplicity.

Very good prices and good shipping prices. found my parts cheaper then any place else. Thanks to Autoplicity for filling my order #8498 of 4/02/12 quickly and accurately. I will be back.

The item has not been delivered yet. But the email updates are great. And I found this much cheaper than elsewere.
