Fired up my newly rebuilt motor for the first time. Let her idle, check for leaks, get up to temp for about 10 mins then shut down... What's the general consensus on doing the break in oil changes? Should I dump the oil in there now before taking her out for the first time, or should I put maybe 20 ish miles on it? Thanks as always guys!!

 

I didn't use any break in oil. Tossed 20w50 in, started it, let it get fully warm and checked for leaks then it went right on the dyno and made 700whp.

I changed it after the dyno
