Engine Break-in

Years ago...the motors that I built I never did the break in run! Did pre-prime the pump,set the timing as close as I could...but never did bring the rpms up and hold them above 1800 and the very it up to what ever...Never did have a cam failure...
When we lite off the new 383 in my son's 68 Dart..we will do the cam break in....
Anyway live and learn...
