are the camaro engines lt1& ls1 some of the toughest engines around? Ive owned a 94 and now own a 97, and with both cars i would occasionally (sometimes more than occasionally) 'drive it like i stole it' and the engine in my 97 seems just as powerful now as the day i bought it (the stock transmissions suck though) same with my 94, but i only had that one for about 20 thousand miles
