what weight oil should I use for breakin? I know i need to use organic oil, but should i use a more viscous oil than 10W-30? Also, for those of you who rebuilt em yerself (Dino) did you unplug the ignition coil and turn the car over a few times to get the oil flowing before you started it up for the 1st time? Thanks for the help, and if you have any additional tips or precautions for breakin, please share em.

Ill just tell you what I know (and did when I got a new shortblock). You have to change the oil after the first 500 miles and then change it again at the 1500 mile mark. Also you should not break the engine in on the highway. The reason for that is, that you shouldnt keep the engine at any rpm level for too long, you should modulate.
