There are several factors that I think the jury is still out on.
Cooling- Not sure I want to worry about making sure the inspection covers are sealed to prevent water leaks inside and outside the block.
Also what about beak down or vibration of the seal over time?
Cylinder Bore Coating - This also worries me, first thought that comes to mind is the Chevy Vega.
I know the coating has improved and yes it is used in racing motors but as Mike pointed out there have been problems with breakdown due to poor gas quality. Recoating is very expensive, how often would the cylinders need to be reinspected?
Price - So its basically the same as a Shelby block, right? Which now has an established history and has been going through several years of improvement.
Weight - Would like to see what the total weight is of a complete motor pan to carb compared to a Pond or Shelby.
I am sure that you will get several lab rats on this site who will want to be first to try it out. Should be interesting to see how it unfolds.
