grand am cam> TREX, G5X4, Magic Stick I see fastest cam only cars running the TREX and X4 and the MS, why not the Grand Am? It's a 239/251 .570/.570 on a 106!!! Just put some 1.85 rockers on it. Why is this not a more popular cam? Just lack of popularity? That one video with the GA cam ripping apart the Cobra(in an A4!) got me sold.

I meant to put a ? at the end of the statement, my bad. I'm not saying it actually is better than the aforementioned cams, I was just wondering why it isn't more popular is all. I'm not getting the cam based SOLELY on the video I saw either. All the mentioned cams are huge, and think that they would all work. Softer lobes, lower lift, and a bitch to idle. My X2 idle is set at 1000, idles great.

It just won't make it as soon as a cam with a harder lobe would. Soft lobes tend to come on hard in the middle of the rpm range because the valve isn't coming off the seat near as fast. Softer lobes also tend to hold peak power longer because they have more advertised duration, whereas hard lobes tend to fall off hard after peak HP because of less advertised duration. With that in mind, Soft lobes could have the tendency to make more peak power because they can turn a few more rpm's. In most of our cases though, where looking to make power early in the rpm range, so a cam that gets the valve open sooner, makes the same power, just faster. This usaully comes at the expense of a few peak HP, but who cares casue your making more power "under the curve", and that's what counts on the streets.
