Concerned about my cam choice. Opinions.

if you lower the duration too much you might up the dynamic compression a bit...

so you will probably get more power but you may be putting full tanks of 110 not the half tanks. it's hard to say

KB has a compression calc on their website that will calc the static and dynamic comp ratios. but you need to know bore / stroke / head cc's etc as well as the cam specs. if you know all the info check it out and compare the before and after
