Not Ranked
Duration would be in the ballpark. Hard to comment on lift and LSA without knowing if any head work has been completed. Porting changes a lot of things including the duration split and even the LSA itself.
For most small displacement road race engines, a tighter LSA will make a huge difference in torque and how much throttle response is available down low.
