Illegal. Can not run any aftermarket block be it Ford or Chevy. It has to be a passenger car or truck block. A boss block is just an aftermarket block made by the factory just like the bow tie blocks are.BUY A NEW BOSS BLOCK ....... DON'T WASTE ALL UR internal or your car..When I bottom END COMES OUT OF THE BLOCK AN OIL'S DOWN THE TRACK ...just my opinion .
