FYI, I reached out to Coast High a few weeks ago, and their response was they are only building Dart blocks right now, and they are months out. If you provide your own block (any block), they can turn it around in a few weeks.I had my 351w block built as a 418 by Coast high performance. This was 16 years ago and it is as good as new today. They can custom make the pistons for any head and compression. I had them install my cam. If you can install the heads etc and degree the cam a short block this is a great way to go.
