ok i was wondering how long would i need to break in a new gm 350 engine. what oil should i run for initial break in? Should i run a synthetic with break in additive. and then switch back to regular oil or should i run synthetic for 40,000 miles then go back to what i was using which was valvoline max life. just curious because i need to start gathering parts and oils n such because i got a loan from my moms bank (i have no credit) and they had the check printed out before i even completed the app. and my bank took 4 days to tell me no. wierd huh....
