Reply to "igintion timing for high comp engine based on roller"

we will see..did go back into my design work ..
I used a spread sheet and the crane cam is recommened for 9.5 to 10.75 Static. If I use Deg duration which is 284 or 360 - 284 = 74 it gives me 7.55 Dynamic. I got confused as I was playing with different cams 2 years ago when I kicked off my engine work. So hope all working fine.
Here is my metric: Comments?
