well...people say drive and break in...others say "drive it like You stole it". Builders put far more money into a race car motor than We ever will...bolt it on a dyno and run it full out. So what is right? what about the "crate" engines that come with dyno slips?

My opinion is if it don't leak, don't make unwanted noises...enjoy it as long as You're under the redline.

In the 60's....very few "broke" a new car in by babying it. Usual left a "patch" when leaving the dealer. oh, patch = peel in OMF talk.

also...laying rubber...smokin...etc
