difference between these two cams?

There is a alot to picking a cam,the bullet obviously has some agressive ramps to be at .574 lift with a 236/242 @ .050 duration requiring at least the same valve spring or more as the lunati.It obviously has a bit less duration at .050 but as moper said it probaly makes it up-or more at .200.I liked the lunati initially because it looks to be slightly less agressive but would behave similar in your build but since you want a hot street car the bullets probaly the best bet.There are always two ways to skin a cat but if I can get similar performance between to hydraulic rollers but use less valve spring/lighter on the valve train with one thats the one I want.
