I'm sorry isn't matt built part of strictly mt??? W.e. the case is I have emails saying you or whoever assembled the motor for a friend which in turn sold it the person I bought it from. It doesn't matter anymore I took care building my own engine. im sure the previous owner wouldnt mind chiming in as proof as well. That being said do you want to purchase the block? If not don't come on thread saying you didn't assemble anything, when I don't even kno who you are, but yet you know you didn't assemble a block you haven't even seen to say otherwise! I went about this nicely...stay off my post if your not helping the cause because there's a lot to shed on this subject.
