Found this article to be interesting on how to break in a new enigne.
yup
start it,check for leaks & nioses,drive ez down the road for a mile or two,turn around & gas it!
yep
thats how I did my NA motor. Ran it for 20mins to set everything. Changed oil. Made sure it wasnt over heating and then ripped it to 9krpm.
I was a lil more cautious with the new motor I was nice enough to give it a few hundred miles before boosting it. Checked the motor over. Compression is good and its taken to boost very nicely
