Cam ID...?

[JB]

Can anyone help me identify these cams? Who ever ground them eched the following numbers over the old numbers making them very hard to read but here is what I think they are:

Left: 993 105 247 90

Right 993 105 246 90

I was told they might be 3.8 RSR cams but need to verify.

Thanks,
JB

Did you get the last 2 digits round the wrong way ?

PET lists

993 105 247 09 ... M64 21/22 23/24

993 105 246 09 ... M64 21/22 23/24

If so, they're for a 3.6 285 bhp model

Andy, the way the numbers are placed on the end of the cam indicates a 90. I was told by another person that the 90 is the 3.8 RSR cam. Do you have any way to verify the 3.8 RSR part no.?

Thanks,
JB
