Dart Big "M" 396 Sportsman block...

Arnold, I've been getting mine from Dart through Liberty, but I do have a second source now. I spent a while with Rick from Dart yesterday talking specifically about the "396" block. I'll have to ask Jimmy more about his that we got last summer. Rick was telling me the latest version has non siamese bores, unlike the block they sell with 4.250" base bore. When I started talking to Dart about doing a 396 block, they were originally thinking they could just use the big bore casting, and having them start at 4.125", but I was told that did not work they way they had hoped, so they built a new set of patterns and boxes to do a 4.094" bore block. The 4.250" bore block is the same as the 4.600" bore block.
