GM Flat Tappet Break In Frustration

[Ozzy2013]

Your needlessly worrying you would know by now if you had wiped a lobe as long as you didn't use synthetic .If you ever do it again run it 20-40 minutes at 2000-3000 rpm after you prime the oil pump .And change the oil and your done!Thats why its a good idea to use a known good carb even if you borrow one the initial break in is critical so you want it to run smooth .I've even taken the inner springs out of the heads to break it in if you have hi spring pressure .Only lost one cam in 35+ years of breaking in 30 or more motors i was 16 and dumber than a rock .ha ha
