The Cam was sitting at 121.5 ICL at tdc . this is a 04 5.7 with 09 Eagle 5.7 pistons and eagle heads.. 8 degrees from the 121.5 figure would be 113.5 ICL....Just out of curiousity I advanced it one tooth and put the ICL at 107.5.. Got to be a what to move it and even if I do, I will have to check the intake valve to piston clearance . At this point before I go further, I am wondering if its even worth it or find a cam with different specs.. Anyone one here got any opinions on this
