You are better off stroking it. The 400 has 4, and 1/8th inch bore. It also has siamese cylinders to accomodate the larger bore. And, the water does not use water to cool. It has steam holes, as the cylinders are too thin to run watrer, so, remember to have your cylinder heads drilled out for the block. To bore that motor, you would have to sleeve the cylinders, then bore them out. Very expensive.
