Matt, it depends how good the stuff is on it. is it all chinese shit?? like chinaturbo 16g and chinabov?? how rusty it is etc. etc. try to get some pics!!! either way you go ... just replacing the rods and rod bearings or rebuilding the block, its gonna take a little time its not like changing an air filter! 800 sounds nice, but remember the old saying...you get what you pay for!
