So the 2008 bullitt came standard with the MX5000 pistons. They only had enough for the 2008 the 2009 got the MX1000. So I am going to up my compression.
Just an FYI and how do you raise compression on a stock bottom end?
machine the heads or get domed pistons. or get new heads. basically exactly what lonepalm said so it will cost you a few dollars. why do you wanna raise the compression? if you go F/I youll just have to lower it again anyway
