The EP-1830 is the most widely applicable electronic distributor in the GM series -- a direct OEM replacement for the standard GM 5.0L (305 CID) and 5.7L (350 CID) V8 distributor used across an enormous range of Chevrolet and GMC trucks, SUVs, and passenger cars from 1987 through 1995. This single part number covers the full-size Blazer, C/K pickup trucks in all configurations, the Camaro, Caprice, El Camino, and G-series vans -- essentially every GM full-size vehicle using the 305 or 350 V8 with the TBI or early EFI management systems.
General Motors made a big mistake by cutting corners on the original distributor. The engine will far outlast the factory installed distributor. If you are going to replace this part, why not use an upgraded version made out of cast aluminum? The EP-1830 addresses this concern with a cast aluminum housing and improved component quality over the factory plastic-component Vortec distributors.
The EP-1830 replaces the broadest range of GM OEM part numbers of any unit in the EP catalog: 1103838, 1103698, 1103749, 1103791, 1103827, 1103839, 1103880, 110-3952, DST1830, 30-1830, 84-1830, and GM04. This wide cross-reference reflects the number of production variants GM produced across the 5.0L and 5.7L application range during the 1987-1995 model years.

C/K truck fleet maintenance

Camaro and full-size Chevy service
Service shops maintaining 1987-1992 Camaro and 1987-1990 Caprice stock EP-1830 for the standard GM 305/350 distributor replacement.
High-volume GM V8 wholesale
The EP-1830 is the highest-volume single SKU in the GM distributor range. Wholesale distributors maintain substantial stock to serve the enormous population of 1987-1995 GM V8 vehicles still in service.
Installation guide
Disconnect battery. Mark distributor rotor position and housing alignment -- critical on EFI applications where timing is computer-controlled. Disconnect 4-pin or 2-pin electrical connector. Disconnect vacuum advance hose if present. Remove hold-down bolt and withdraw old distributor. Lower EP-1830 into position with rotor in the same location as noted. Tighten hold-down finger-tight. Reconnect connector and vacuum hose. On TBI/EFI applications, timing is computer-controlled and does not require adjustment if the distributor is installed in the same position as the original. Approximately 30-45 minutes.
