Darts are a high quality block but you will spend a lot more than you think. They must be bored, honed and I feel surfaced before using. If a shop does not know how to bore this block properly, the sleeves will raise up during the bore. Then it gets surfaced back to flat. When you start the motor, the sleeves will drop back down to their original spot and will cause the head gasket to blow. One solution is to bore with a deck plate on. There is more to this block than meets the eye, so all I am saying is just be careful if you choose the Dart.
