I found this on the internet from AI (I think my Crane Fireball Cam had FC on the end)
Based on available Crane Cams data, there is no direct part number listed simply as "FC6". The "FC6" designation likely refers to a Crane Fireball cam, a series re-introduced with tight lobe separation for a distinct sound. For specific applications, similar Crane Cam options available on Summit Racing include:
- Hydraulic Roller (e.g., 119561): Designed for excellent low-end/mid-range torque and daily usage.
- Mechanical Flat Tappet (e.g., 113861): Solid lifter style with 3,400-7,200 RPM range.
- Fireball Series: Specifically reintroduced for classic performance sounds.
Please check the exact stamped number on the cam (usually on the rear journal) or the full 6-digit part number for precise specs.
EDIT: Hmmm the cam say Erson on it...doesn't it. Never mind
