Big Block Chevy cam ID
 

I know it is a long shot but I'm wondering if anyone can identify this Big Block Chevy camshaft. This just came out of a 1967 427 engine that was built in 1969 by Summers Bros and was never started. The engine was built like a second design 69 L88 with GM open chamber pistons, 7/16 full float rods, etc. Based on how the engine was built, I thought it was probable I would see the GM 180 camshaft installed since all the other parts were GM L88. That could be what this is but all the ones I have seen have the whole part number or 181 stamped on the rear. The only other clue I found was a set of early Sig Erson solid lifters in this collection of parts. That doesn't mean much since there were parts from a couple engines in this collection.

Can anyone do magic and tell me what this cam is based on the pictures?


Thanks,

Jason

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
