the cam specs ; intake: cam lift.370 valve lift .629// exhaust: .374-v .636 with a 108 lobe center 83 deg overlap. this is a solid flat tappet cam, new with new lifters running a timing gear at 0 deg timing marks. ( stock marks ) pic one is of set up of no.1 ex valve @ zero lash, #2 pic is of full open and shows the problem how its coming out of the cup. #3 is of the lifter sweep at 4 full revolutions. i had to push it back into place so it didn't pop out of the arm cup. ive tryed this at many differnt push rod lengths to get a near center this is the closest that ive gotten to center for the sweep.
i dont want to grind into the rocker arm if all possible, but i have yet to find any other solution at this time, when it poped out earlyer i got out some feeler gauges and a .0120 sliped in ther so i figure at about .0240 that should give enough clearence if i have to grind on it. what ya think.
