More aggressive than XER lobes? Are these the lobes the new thumper cams use?

Yep more agressive, and more lift!!! Comp recommends dual springs

i am not sure what the thumper cams use

Attached is the DCR spreadsheet i use and the master lobe specs I found on Tech.

The cam i am looking at for my new Forged 5.7 is:

227/227 .614/.614 @ 112+4
+3* of overlap
With my new motor -5cc pistons, stock LS1 bore and 58cc combustion chambers yeilds
CR of 10.85 and DCR of 8.51

Sounds like a great daily driver cam! Haha

Hopefully you won't have to be swapping out new springs every year
