Trying to track down a tapping noise in my 69 430. Removed the intake to remove the lifters and push rods. Push rods roll straight on a plane of glass, lifter bottoms and cam lobs look good. My question is should I be able to push down the lifter plungers manually with my hand ? All 16 plungers do not move. Thank you Jerry
High Jerry, Dont know if you found problem yet? I thought I might tell a story of mine back in early 80s. Had sbc doing the same thing found a lifter loose in it bore.
