It is under rated. Not nearly as much as the new cars. Mine isn't an LS1, it is an LT1. I have seen only a couple of freak automatic LT1s make more than the factory rating of 275 at the tires. They had headers and tuning. Normally they make 235 to 250. Maybe I need to put a 2000 model front clip on mine, and an LS1 in it. The aluminum head LT1 Stockers have a lot of work the tech guys can't seem to see. The set I flowed weren't all THAT much behind my SS ported heads. Nothing like factory castings I have tested. That, of course, is reflected in the hp they have earned in Stock. :-)
