Depending on the piston crown angle and the stroke.I think 67mm bore and after have to be cut for the bore size.So being that you run a 4mill crank (assuming hot rods)and have 66mm pistons,i'm gonna say yes.Your gonna need to know what pistons you have to get the correct dome size cut for the specific CC you want...blaster pistons have a 9 degree crown angle so if you need to have domes cut they only run $85..Call F.A.S.T or Noss Machine they can let you know for sure on this
