if i punch out a 7.3 30 over can i use stock parts like crank and cam and stuff that dont come in an over bore kit ? im also new here guys so hit me up im in newyork

Yeah a simple overbore shouldn't effect any of the other stuff. I'm not too familiar with 7.3's but I can't imagine a .030" being an issue. Usually main concerns when boring out are cylinder wall thickness, and how close you come to water jackets and what not. I doubt it's an issue at those sizes though. Anyone know if 7.3's use sleeves or are the bores part of the block?
