This is the spring my installer and builder are recommending I get. I had a sponsor do a custom cam spec and they recommended at 231/238 .598/.585 with HUC/XE lobes. 6600 shift and 6800 limiter in my LS3 build.

I know the defacto standard on beehive seems to be 1518, but how do you think the 1211x compres to the 1518?
