how haven't you blown out your transmission yet? the 97 se and gt models had vacuum controlled transmissions that most people on here try to avoid like the plague lol. kudos, but that's something you might wanna keep in the back of your mind, especially with the 20's on.
i personally don't have any experience with cams, but i'm guessing what the mean when they say it isn't "friendly" is that it won't allow you to reach the full potential of a supercharged setup like, say for example, a more common s1x cam. i'm sure it will work, but you should probably think about finding somebody good with a tuner and have a custom tune done. even if it isn't necessary, it couldn't hurt. and, if i remember right, if and when you swap, you'll lose the HV3 insert and possibly the throttle body you have now.
