bored
 

lol, this thread has double meanings. A) im bored as nutz B) i want to know what kind of power gains i can expect from over boring/reworking the head...any feed back would be appreciated-i may also do cams

i can really loose power? from increasing bore?

i'd imagine..since a larger bore would be too wide to have faster airflow velocity. i think a turbo would make up for it. something like that.
