I am building a 383 SBC to put into a 93 S10 and was wondering what some good break-in oils are? I know I will want to run a dino oil for the first couple changes and I'd assume I'd want somthing with a high moly content. I plan to change the oil 3 times in the first 1000 miles (after the cam break in, at 500 and at 1000) after that I plan on running Schaeffer Supreme 7000. what do you guys think? and what weight should I use? It will mostly be street driven (with the occasional visit to the track). It wont see many, if at all, days below 50. Thanks, Jeff.
