anyway i am planning to build a 347 but dont know what i need to get done to my block? Do i need to get it bored out 30 for a 347 stroker kit or what.
i have called some shops around me and they wont help unless they do the whole motor top to bottom.
so a little help would be great thanks

The block needs to be notched on the cylinders for clearance from the bigger crank, then balanced to i believe 28oz, so you'll need another flywheel.
Your better off getting a crate motor, or shortblock from d.s.s, then put the heads on yourself.
why 347? Id go 331.
good luck.
