Was looking for LT1 vs LS1 torque graphs when I came across this link of an old discussion.
The key post is Fred's (Injuneer) who is a well known guy on many Forums and always comes up with quality answers to most everyones questions. The topic was LT1 vs LS1 low end torque which has been a subject of debate on many forums including this one. My original search was for a Graph that I seen in a Magazine years ago that overlayed LT1 and LS1 Horsepower and Torque figures I distincly remember seeing the power out put of the LT1 being similar if not slightly better then the LS1 below 2-2500 rpm. I never found the graph but this discussion, specifically the post by Injuneer is quite enlightening.
