Interesting. Thanks. The seller gave me some specs from his memory, and he said its meant to be 8.6mm lift or so, and 274 degrees duration. Not much lift compared to other mild cams, and I was wondering if its measured at the cam lobe, whereas others may be measured at the valve? It probably just doesn't have much lift. The base circle doesn't look like its been cut much, but some has been taken off the top of the lobes definitely. Was probably on an L18 or smaller.
