New 440 Source 4.500" Bore RB Block

You can call them on a 400 block, but they have no intentions of doing it until after they recover from the RB project.

If they had a 400 block ready to sell in a year I would be surprised.

Thanks Tom it would be just to show interest.
Im hoping my build im doing now will last a few seasons.
