Will this alternator physically fit my Chevy 350 or SBC engine?

The BDELI 63 Amp one-wire alternator is designed to follow the standard GM 10SI/Delco mounting and pulley positions used on many Chevrolet small-block and big-block V8s. It should bolt up to the common brackets and pulleys used in classic and replacement installations, but confirm bolt pattern and pulley offset against your vehicle before ordering.

• Direct-fit mounting pattern compatible with most GM 10SI applications
• Designed for small-block and big-block Chevy layouts (Chevy 350, SBC, BBC)
• Check pulley type and spacing to match your belt system
• Compare part numbers: 7127SEN, 334-2614, 1100125, 400-12370

How do I wire the one-wire self-exciting alternator?

This is a one-wire self-exciting alternator, so it requires a single heavy-gauge output cable to the battery/starting circuit and a good engine ground. The alternator will begin charging once the engine's electrical system provides initial voltage; a short ignition feed may be used during first start in some setups.

• Single heavy-gauge positive output to battery or starter solenoid
• Ensure a clean, low-resistance ground connection to engine block
• Optional ignition trigger only needed for some long-dormant systems
• Verify output wire routing and fuse/links per vehicle electrical standards
