Back at it again this morning. First thing was to install cam gear straight up and advance the crank gear +4 degrees with my 3 way 3103 timing set. Found TDC and measured intake lobe. Shows 107.5. Odd that it does not match my original 106 value in post 144 and it's also +4 from yesterday's dot to dot 111 measure. A 4 degree crank advance should be 2 degrees at the cam. Unless Comp uses cam degrees. Doesn't specify on their website. Summit says both. Pushing forward on my way to 106 I retarded the crank gear -4 degrees and installed the offset cam keyway advanced (it was adding 10 degrees yesterday). Set TDC again and now I am measuring 105 degrees on the intake lobe. I am happy with that and will now measure lift, duration and cam timing open/close on intake and exhaust but I wish I understood why these numbers are not following what you would think to be logical. I would also like to know if it is OK to run installed -4 crank and +10 offset key at cam getting me where I want to be. YES I understand that this is not the textbook way to do it so no lectures please. Just want to know if I will break parts.
Thanks.
