This is the routing diagram for a 454 engine using v-belts only, not a serpentine belt.
The following abbreviations are used :
- C - Crankshaft
- S - Smog pump (A.I.R.) system
- W/P - Water Pump
- Alt - Alternator / Generator
- A/C - Airconditioner
- P/S - Power steering(In some installations also includes the brake booster pump)
This particular setup is most prevalent in motorhomes. Refer to the diagram.
Diagram

utilizes the 1st groove on the power steering.(belt no : 15415)
Diagram

pump pulley, the A/C pulley and the 2nd groove on the P/S pulley.(belt
