A friend of mine has a 440, rebuilt, stock stroke , forged crank, stock rods,6 pak pistons,




he said stock rods , 6 pk pistons. It is possible to interwnal balance 6pk rods and heavy TRW pistons , not a lot of weight needs to be adde.

I for the life of me do not know why chrysler external balanced those engines .




Cast is less dense than forged so there is less weight in the counterweights. It would have only taken a slight increase in diameter to be able to neutral balance the cast motors, wonder why they didn't?
