Re: Hardblock?
If you had the choice , wouldn't it be better to start with a good block , like a Bowtie or Dart ? A filled block has other problems like bores going out of round , or cooling problems when racing . What does a filled block weigh , compared to a Bowtie block . Plus after you where it out for bore size , it can be sold to someone that can use a bigger bore size . In the long run it might not really cost more to run a good block .
