Cam degreeing help me understand!

Ok, if you install it on a 106 ICL like Kenny has on the card with your numbers your @ .050 opening point will be 5 BTDC. That’s 2 advanced on the 3 degrees he has listed.

At that timing you’d be putting 2 of the 4 extra degrees on the opening side and 2 on the closing side.

If you think that extra 2 degrees is going to affect bottom end power, you can install it on a 104 ICL and that would put all 4 degrees of the extra duration on the opening side and keep the closing point at 35 degrees ABDC.

IMO, IVC and by effect EVO (which affects blowdown) and more critical that the other two timing events.

Me, personally...I’d put it in on a 104 ICL and keep the IVC at 35 degrees ABDC and just open the intake valve 4 degrees sooner. EVO a will also be 4 degrees earlier and that will help bottom end. Late IVC and late EVO move the power curve up in the RPM range.
