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...
