Cams on 3sx

I'm curious, has anyone here replaced their camshafts with the ones on 3sx(or anywhere else)? I've been talking with a guy who builds drag cars, and he was saying that from his experience with drag cars camshafts are one of the better upgrades for HP. Now in his cars where there's plenty of engine space, and cheaper parts he says it's a pretty simple process altho he admits he wouldn't dare try it himself on our cars. I got to thinking, with the effect the upgraded camshafts would have on fuel comsumption, and the fuel/air ratio of the turbos. Is it a worthwhile upgrade, or more trouble than its worth?:licka:

Oh, and I'm not talking about the "Ultra Weld" or anything, just one step up from stock, so that I would have to do little to no other mandatory upgrades for those camshafts.
