Your engine will be retarded !

The intake valve opens later and closes later. Since it closes ABDC that's a hair less compression the motor will make. Likewise the exhaust valve will open sooner, releasing combustion pressure sooner. All this equates to a loss of power.




You have it backwards. If the intake valve reaches peak lift earlier at 105* ATDC vs 108* ATDC

Then it is indeed advanced and not retarded.

For the OP, if thats where your at. Thats not a bad ICL area. IMO 101* to 106* for alot of engine combos is a good general ICL. mike
