ICT Billet SBC Accessory Drive Kit For Double Hump Heads
This kit is designed for SBC engines with double hump or standard heads and uses a V belt system with a long style water pump. Best for builders seeking a straightforward, USA-made billet solution that emphasizes belt alignment and strength. It is suitable for 305/327/350/383 and similar V8 layouts. A single limitation: it assumes compatibility with long-water-pump configurations and a traditional V belt setup, which may not fit serpentine systems.

The design focuses on easy belt tensioning through a slotted tension setup and includes durable steel/aluminum construction with anti-corrosion properties. It’s a solid pick for a reliable daily driver or a light performance application. Choose this if you want a balance of affordability and belt stability; avoid if you need serpentine-belt compatibility or a short water pump configuration.

- Material and finish: Billet aluminum options offer light weight and corrosion resistance; steel-aluminum combos can balance cost and strength.
