Engine Break-in

Make sure you have plenty of oil pressure,use a good oil i prefer 15w-45 diesel and a good filter,set timing as close as possible,fire it up check timing set idle speeds,check for leaks,take it out and drive it at various speeds,this also helps the rings to seat faster,i have heard of more people ruining cams sitting there with the car idiling at 1800-2500 rpms,my engine builder frowns about that stuff,i've yet to ruin a cam doing it his way......
