SBE 318 basic rebuild +CAM , INTAKE, HEADS, expectations?

since someone mentioned Whiplash cams.. i am curious if anyone has ever seen one on a dyno or at the track? I have seen a lot of videos about how amazing they sound but not how they run..
The specs on the cam indicate improving low end torque and overall performance, win win for a low compression 318.
I now several guys using the Whiplash, one with a 360 and another with a 400, both said the cam made the low compression engines into a different beast.
