Only if you run baby cams whistling
Big cams starting opening @.050 from 40 BTDC to 55 BTDC with no advance shruggy
The LSA affects the intake and exhaust lobes opening and closing, a cam that is ground on a 112 LSA with 250 @ .050 on both lobes will have the intake opening @ .050 further away from TDC than the same lobes ground on a 108 LSA scope shruggy
