Break in period? I just got the motor back in the car. It runs great, I finally have a heads and cam setup + a built bottom end 
. The cam is my old arlington motorsports grind that my brother gave me(it was in my pewter z28 when i sold it), the heads are patriot stage 2 ls6. Im using stock crank, wiseco coated forged pistons stock compression ratio, esp eagle rods, arp complete engine stud kit etc. I put Gm break in oil in it, how long do i run the break in oil and is it ok to break the motor in while its untuned?

JMHO....
