i am about finished building a 347 n/a engine. i have 306 block in my garage that is lying around and i just recieved a complete 347 kit for free. my question is will this kit go right in the 306 to make it a 347 or do i have to get motor work for this kit too work. if it helps the pistons are .030 for the 306 and the 347 kit. thanks
