I'm really thrilled with the results of our own cams here at PCM of NC, I'm about to get this one added to our website as soon as I can think of a witty name for it (harder than you think LOL).
I've used this in a few customer cars and now in my own and it's perfect.
With an intake & headers, stock heads, it makes 460-470rwhp. With heads it made 496 rwhp (SAE) in my car and 498 rwhp (SAE) in a customer car. Driveability is really important to me, so I wanted something that I would enjoy driving for more than a week. This cam has great manners - no bucking, surging, downright near-stock driveability characteristics. Sounds great and it picked up power everywhere in the dyno graph, we gave up nothing!
I totally agree with everyone else in this thread - the package you listed is not a good match for an LS3. Contact a sponsor and let them help. We know better than summit does.
