both set of pistons are cast ...so staying with cast ...and i guess no need to source a flywheel before i send the crank out for balancing
these are the rods both free floating
Use forged. What's it going to cost extra overall? 1969 340's had forged pistons also. I was racing 340's in 69. Like the song says, the best days of my life, summer of 69. Yesterday to me.
