May want to contact Carl Heffner before you have Ash build an engine for you. Better yet, Burton (PA/FL) his year long torture was more recent. Wait no... Carl paid for his motor two years before Burton's got started... and Carl was refunded after Burton's year was up.
Did I forget to mention that Ash threw such a wrench in Carl's project that he sold his Z and took on another project in the process... oh yeah... that too...
