the ls1 cam is a mild cam. I likely would not go to the trouble of a cam swap if that's your cam choice. yes you cam buy a hotter comp cam with the rear sensor provision. and that is a good choice. keep in mind the hotter your go, the more driveability you loose. also the hotter you go, the more likely you need hardened pushrods, and dual springs, better retainers and locks, and then likely a better tq convertor choice. but im with you, I would likely give the trans a good looksee if it is at all questionable long before a power adder. have fun and happy motoring.
