this has been discussed so many times before that its not even funny. but instead of being a dick and telling you to search like you should have done before posting this, ill answer you. you can technically run 10psi on your stock block safely but that is pushing it. the max that you should push and not have to worry is about 8psi. but you also need to find out what compression your engine is at so you know that it can even handle boost in the first place.
