guys, i went to dyno day for an f-body meeting with my brother, most of the LT1s were in the range of 235-260 rwhp, all the ls1s were between 280-325 rwhp, so there is a big difference in power numbers, the lt1s were modded but a majority of ls1s had only catback and an airlid, thats some serious power. I knew a guy that had a stock SS with 300 Rwhp
