350 to a 383 or even a 388?

[pimperout]

i have an old 350 engine in a parts truck of mine it runs nicly but i would like to put it in my good truck. i figure if im takin it out and my other engine runs now why not take my time on this 1 and make it as big and powerfull as i can so i would like to know first what is the absolut largest you can bore out a 350 with no complications .030 or .060 i have seen pistons for .060 over but some friends of mine think that is to much and it may blow out the walls of the cylenders under pressure. and also what are your reccomendations for getting as much HP out of the motor as i can? thanks
