David:

That is really cool. Upgrading to this block would probably cost less (cost of new motor minus sale price of my now obsolete Shelby aluminum motor) than my wife spends on shoes in a year, so it seems like a reasonable purchase. It might be a little soon to ask for more, but are billet heads in the near future? That might bring the weight of a BB head down to that of an SB head. Times 2, that could save a good amount of weight high up on the motor.
