Crane's energizer cams

Hey guys, i have a crane energizer 272, .454 lift cam...just wondering what the performance level of this cam is and does it have enough of the choppy sound im looking for also, or even if anyone has a video they can post?
My main concern is that it wont have the sound and performance i want but also i do plan to use my Demon as a driver more so than a racer or even street and strip...read up that this cam gives good gas mileage too? Thx Brad.
