Hi guys , its been 21 years im in the hobbie but the cars that i drove always had the engine rebuild or were roller cams ( magnums ) i never did a break in myself , my young cousin bought a 360 from me and a 69 valiant project, we want to do stock 360 flat tappet camshaft break in, ive read all the step and i bought him a set of melling lifters ( 340 replacement) and ive seen plenty of rv and stock 340 replacement grinds on the net for cheap, i know that theres big chances that the cam or lifters can flat our or break but im willing to take the chance, maybe my 1st and last flat tappet break in , always been a magnum engine guy. I would appreciate if i can have some tips , oils , special tips , lubes etc , it makes me nervous a bit , but ive seen videos and read so much on these that it seems that unfortunately all the flat tappet cams are from michigan and all the test were clear that the cams were very strong and its the angle of the lifter that was problematic , but onces in a while guys look to be okay with their break in and ive read that even in the 70s 80s guys had problems with flat tappets too , my cousin is 19-20 and on a very very tight budget
