There have been claims of possible builds using the cast iron block but we have not been aware of any complete and performing engines.There have been a few whom have struggled and got their engines up and running.We would like to here of the build process and results.There certainly is a market for a good strong small block foundation.We have been building a lot of SBs with supplied cores and restoration blocks.It would be great if Kent can get his production available with minimal corrective machining cost.We would certainly a prospective customer.
