I have an LS block got it on ah trade. The pistons are all some what down. two are half way up, an two are all the way down. Some one told me its blown, IDK tho. Just wanted to see if any one knew for sure its blown because of the pistons. The only reason my boi said its blown was simply because of the position of the pistons. Any feed bak about this is really appreciated. Holla bak
