... first, searching the archives, it seems like the best break-in would be an aggressive break-in... similar to the one found here... in this it says that ring will seat within the first 20 miles... in addition, most of the break-in is done in the first 200 miles... so my question is how do you break-in the engine aggressively if it is not yet tuned?... problem is the nearest dyno is 50 miles away... just curious if anyone has any ideas... i know there prolly isnt anything i can really do... anyways, lemme know... thanks...
