EP-5052 Electronic Distributor for Chevrolet 400 CID V8 Classic Era

The EP-5052 is an electronic distributor for the Chevrolet 400 cubic inch small block V8 -- the largest displacement version of the Chevrolet small block, produced from 1970 through 1980. The 400 SBC was used in C/K trucks, full-size Chevrolet passenger cars (Caprice, Impala), Monte Carlo, and various other GM platforms during the emissions era as GM sought to maintain adequate power from a large displacement with lower compression.

The Chevrolet 400 SBC shares the same basic block architecture as the 350 SBC but has a unique bore-stroke combination (4.125 in. bore x 3.75 in. stroke) and specific cooling and oiling considerations. The distributor for the 400 SBC is the same basic unit as the 350 SBC in most cases, but production year and engine management configuration differences may result in different OEM specifications for certain applications.

Verify the OEM part number on your specific 400 CID distributor before ordering to confirm exact fitment.

Every EP distributor is manufactured under ISO 9001:2015 certified quality management. Each unit is individually tested for cap-to-rotor alignment, pickup signal function, shaft seal integrity, and connector specification before shipment. CE-EMC electromagnetic compatibility certification, UL listing, and UKCA conformity mark confirm compliance across all major export markets. Units ship complete with cap and rotor -- no additional components required for installation.

Founded in 1999 in Ningbo, Zhejiang Province, EP produces over 300 distributor models covering classic and modern GM, Ford, Chrysler, and international applications. Our GM EFI Distributor range is engineered as a direct OEM replacement for the factory Delco units -- same external dimensions, same connector configuration, same cap and rotor interface -- with improvements in housing material and component quality that address the known failure modes of the original distributors.

Wholesale buyers, Amazon resellers, and automotive service chains source directly from our factory, accessing OEM-quality replacement distributors at factory-direct pricing. OEM branding and private-label packaging are available for qualifying order volumes. EP is part of the Ever-Power Group, also producing couplings and a comprehensive range of mechanical transmission products.
