I bought a cam from a friend with an understanding that is was a Hotcam.
He told me the specs were 207/217 with .525 lift.


On the end of the cam are these numbers "06 43 12" "284" "290/06ENG" and "0967"

The only number I could link to anything was the 0967 making it a stock 5.3L cam. However I havent found any additional evidence towards this so I am asking anyone who may be able to help me to speak up.

I dont want to be putting this cam in my motor or selling it without knowing for sure what it is.

Thanks
