I think you should be the first, unless you have a 1900, then don't.

I could be wrong, but I believe that the 1900 will have difficulty in keeping up with the air volume demands required by 427 cubic inches...

agreed. The 1900 will definitely be undersized for that much cubic inch. Even a 2300 would have a hard time keeping up. For a 1900, we would do a 404 with compression ratio in the low to mid 10's, and with a 2300, we would do a 419 in the same range for compression. This will allow you to keep the boost at a level that produces less heat, and keep a nice flat powerband that doesn't fall off too early because it has ran out of blower.

a 1900 would work well on that too, and we would target something in the 10:1 range for CR.
