455 CID Alernator, A/C & Standard Power Steering
Oldsmobile 455 cubic inch big block engine serpentine conversion kit. This Ultra kit will convert a big block oldsmobile engine from V-belts to Serpentine while adding the option for a/c. The setup uses the stock Saginaw power steering pump with a keyed shaft. The kit is designed to put a Sanden style (SD5H14) a/c compressor on the right side of the engine, and the alternator and power steering pump on the driver side. The kit uses two serpentine belts with idler pulleys to eliminate the possibility of belt slippage. The kits pulleys are the same size as the stock pulleys to keep the vehicles charging system, and cooling system working properly.
- The kit includes:
- Alternator bracket with idler pulley
- Alternator relocator arm
- Aluminum crank pulley
- Aluminum water pump pulley with nose cover
- Aluminum alternator pulley, fan, and nose cover
- Saginaw power steering pump bracket
- Aluminum power steering pulley
- A/C compressor bracket with idler

This setup has a polished finish with clear powder coating to eliminate any polishing in the future. It is also available in Black powder coated, chrome, and black onyx see the drop down button above.
A standard Oldsmobile forward rotation short water pump has to be used with this kit. The setup will also fit Pontiac Firebirds with a 455 CID engine. If you plan on using this kit in a street rod we have a kit available that moves the compressor and alternator up on the engine, please contact us about this setup.
