GR5 comes in here asking about a 340 and some of you guys start into some kind of 360s are the best crap. that's your opinion. whatever. if you can't add some kind of pertinent advice or info, then go take a dump or something till the urge to spread your manure passes.
the teardown and inspection is definitely the way to go. the only thing i might add would be to attach the transmission and a starter to the engine and do a compression check before you tear down the block. the compression numbers might help you decide what your going to do next.
