Thanks for the info, trying to get a good grasp on valve timing for my rig, I have been running 2 cams small and large and trying to figure it out by seat of the pants, Seems a lot of guys are running wide lsa with a lot of advance , still trying to get a feel for cyl preassure,lsa & advance, the simple thing is go with a 108lsa on 104 lots of cams built that way but not looking for much power under 5000, still dont know if 108 lsa in on 108 or 110 on 106 , which one is better for me? Sorry if I stomped on someones thread but the questions are closely related
