That is correct, the tighter lsa will bring the torque curve lower. I ran a 264/272 @ .050, .680 lift, & 106 lsa, in a 430" motor in my Cobra and it was a blast to drive on the street yet very drivable. It was the same cam I ran in my 430" circle track motor except the circle track cam was ground at a 108 lsa because it operated at 1000rpm higher. The circle track grinds emphasize smooth power and wide torque curves for drivability, over max power. Keith Craft has said numerous times on here that he developed a lot his street roller grinds from his dirt Late Model program... I did too.
