Preoil the engine where you pull the distributor, put a length of 5/16" hex stock down to the oil pump and turn it CCW for a big block, or CW for a smallblock.
^^ that^^. takes care of the lifters & fills each particular one to the cup height it is at in the firing order & preoils the rest of the eng & you want minimal turning with a new cam breakin. get the dampener slit at TDC #6 compression & preoil then hand turn crank 3/4 turn back CCW & preoil the other bank & cut a strip of paper 17.082" for a ruler (BB). For a SB get it to 90 deg BTDC #1 compression & preoil & alot of of SB's have partial slits at 90 deg or if not then cut a strip of paper 5.694" then continue on around to 20 deg ATDC #6 compression & use the timing tab as a ruler to go from 15 to 20 deg & preoil the other bank. On the lifters, check preload and do Hughes' lifter body clearance check, the "thunk" test
