Break-in oil choices

[SoulSurvivor]

Do I go for Dello 400 15W-40 or Brad Penn with Comp Cams break oil?

cool she is ready to fire up good luck.Not sure about what oil but I was told to add comps break in oil .I always used 10w30 to break my new engine in.Then i would change the oil right away.My dart will soon come to life in about 3 weeks.

I just broke in my 360, I used rotella 15w-40 and the comp cams break in lube. Main thing is just having the zinc in there to protect the cam lobes. I fired mine for 15 min @1800-2000 rpm.
