Advertised duration is normally referred to as .006 numbers, they are 289/295. Maybe you mean the .50 numbers.

lilbuddy, what length rod and stroke are you planning. 4" stroke? I need to know before I figure for ya. Also is it a 110 ICL advanced 2 degrees? As above you have it a 112ICL.

Its a 110lsa with 2 degrees of advance ground in so I assumed 112 ICL. It's a 4" stroke as well. For those that asked, the cam is a 239/246 .649 .614 110+2.

I might just install the cam straight up as 8.9 DCR is pretty scary on 91 octane. I do have a nice tight quench, but still...

If I was to retard the cam and install it @ 110icl and 110 lsa, what would the DCR be?

So 110+2 = 108 ICL then correct? and 110+0 = 110 ICL?
