Mystery cam, any ideas?

[LATAMUD]

I picked up a forged rotating assembly for my 2003 Viper and it came with a custom grind cam.

Anyone able to decipher the specs? Would this be good for a blower cam or better for N/A abuse? I'm aware the factory rocker arm ratio is 1.7 but the specs are measured for 1.6 rockers.

I contacted Comp Cams and they provided the Cam Card.

Looks like a good mild street cam.

I would say so to be on the safe side. Fair bit of lift in that cam.

I agree, if any age or miles on yours it's a LOT easier now and not that costly.

I got better springs and the cam is installed. Just need to get the heads done.
