Who here is running a bigger cam? What are the specs and who makes it? What cam could I get without reprogramming the computer? HP increases? How bad will a decent cam kill the gas milage? I had the GM "hot cam" for the LS1 in my 1970 Camaro and had stock ls1 programming and it idled fine and everything. Every now and then it would stall though. Im not looking for that "lumpy" of a cam but something to get like 25hp and still be able to drive everyday. What about 1.8 rockers? Any input would be great...

Contact EDC at ls1gto.com, that guy is a cam guru. I've got one of the biggest cams you can put in a Gen3 small block, specs are as follows:
Intake: .603 gross lift, duration @ .050 237 / Exhaust .609 gross lift, duration @ .050 242 LSA is 113, it's called the Magicstick V.3 from Texas Speed and Performance. 400 rwhp is very easy to get, especially in a LS2, simple yet effective modding is all you need. :cheers
BTW, this is what my cam sounds like idling (short but you'll get the idea..)
