440 HP(Six pack rods)

Well.....I stand by my opinion. I don't think a human could tell the difference between six pack vs standard rods. Maybe a dyno could. But to say you could tell a difference I think is a stretch. In the end, I think either rod will work fine, as long as you have a good balance job done. The rods may be "dated" or whatever you choose to call them, but Chrysler engineered them for a reason. Since I don't have a degree in engineering or physics, I sure as heck ain't gonna question it.
