Man even with the extra day Feb flew by!! I think the market for the block is small. I really don't care. We aren't running SCTA or anything else in America. It's stronger that the ''D'' Block. I am only reducing the main and bore sizes to make it useable. From the outside it will look the same as the original. The real limit are the number of OHC head setups around. The block will fot most of them. It's basic design is universal. Not a business for us ..... just something to do to go racing.
