I think it's an old .484 lift cam but I found this one when I was looking for a old Mopar Purple cam and found 2 cams. The other doesn't have any marking's so now I'm confused as to which is which. Anyone know what the HF11H is?

HFIIH?????

HF stands for Hi-Flow series of cams

If so, E410521
306/306 @ Lash Duration (Erson's seat # they use)
235/235 @.050"
.472"/.472"
108° lobe center

Now days it has zero advance ground in it
