From the day I started tinkering with cars and learned to build my own engines, I used to preload the oil system, fire the engine up and let it get warmed up listened for anamolies such as a cam lobe or a bearing. Shut her down and changed the oil. From that point on break it in the way you are gonna drive it. For my street / strip Challenger my 318 ran high 13s and I drove it to work as well as every sunday on the track during the late spring all summer and early fall. Plus all my street antics, which were sometimes even worse than what i did on the track, I didnt top end on the track with a
410 rearend ratio, 1/4 mile speed was around 93 mph she top ended between 130 and 140 mph. With all this abuse my engine would need a new set of main and rod bearings once a year. I know we were thinking about molly rings
but decided against them at the time because seating them in a used block so to speak was more time consuming with a good chance of never really getting them seated with the associated peformance loss if they didnt seat. I did this for a couple of years before I uprooted myself and moved to the other side of the country and my performance building of my car dwindled as other responsibilitys and interests kicked in.
