GM 12370846 cam

Does anyone have the full specs on this cam? Specifically the seat-to-seat durations and the timing events?

Anyone running this cam?

Thanks,
Rob

Thanks guys but I'm actually looking for a little more information than that. I'm looking for lobe centerlines, seat-to-seat duration and where, in degress BTDC/ATDC the IVO, IVC, EVO and EVC events occur. All this stuff should be on the cam card if someone's got one.

Thanks,
Rob

Yes, the units are degree's of crankshaft revolution. If you really want to learn I suggest you head over to CompCams website and do a little reading. They have a nice valve timing tutorial which expains things nicely.
