Ok, I have talked to a few people including about these cams and now I have decided to maybe get a custom grind cam.
I would like somthing with a good torque, strong midrange and enough top end to shift at 6000rpms. Aggressive lope is also a good thing.
I have took the two of comps mild ls1 cams, and changed the LSA on them to achieve the aggressiveness im looking for.
1) 212/218 .522 .529 112 LSA
2) 212/218 .558 .563 112 LSA
Now which one would offer the most performance gains, while at least retaining low-end torque. I dont really want to lose low-end grunt but I have to, I would like to keep it to a minimum. This is also my one and only daily driver.
What would be the main difference performance wise between the cams? And what would you recommend?
thanks guys.

You have a 4.8 right? Are you staying n/a or do you plan on spray or boost in the future? You are stating yoiu dont want to loose any lowend so I am guessing you are runing a stock converter and plan to keep it. If you are planning on staying n/a with a stock converter, I would suggests something lower in the duration with more lift. If you do go with more duration, add in a few degrees of advance. For a custom grind I think this one would work well in a 4.8: 215/215 .53x/.53x 114 +4 That is close to a grind SmokeUr5.0 has on tech in his 5.3 and it seems to do great in his truck.
As for the difference between the two cams above. Since the second one has a more agressive lobe profile and more lift, it should make more power but since they both have the same duration and lsa, their powerbands should be about the same.
