Putting a new cam in my 360

most cam and lifter kits come with a small container of cam/lifter assembly break in lube-the thicker stuff is better, not using some is where U went wrong. and U want to vary rpm from 2000-2500 for 20 minutes, and do not let it idle for any amount of time until it has a few hours of break in run time. go with a cam like a 340 unit-268/276 and .440-.450" lift and 110 l.s.a.
