Camshafts, idle quality, driveability and LSA-REAL WORLD EXP and OPINION

OK tough guy If you advance a cam the intake is open more than exh on overlap , straight up they are open equal, retarded exh is open more than int.If you do a quick check when a cam is advanced the int lifter is always open more than the exh. therefor there is less curtian area on int to try to control reversion .Any other stupid remarks you would like to make?In the meantime go back to your google answers.
