My 68 Super Street Firebird has an Eagle cast crank rotating assembly from Butler with Eagle rods. Makes 660 hp and has been sprayed a few times in the last couple of years with no problems. My 63 Tempest uses the Eagle forged rotating assembly aslo from Butler and has also worked real well. That said, I wish I'd gone with the forged crank in the Firebird also....JUST because I'm sure it's better, BUT I've not had any issues with either.
