?? sixpack rod weights? and ly rod weights?
The six pack rods are not that big of a deal. I kinda like um myself. If you run a modern, light weight piston, you end up just as light or even a touch lighter than a stock LY rod with a stock type piston. The difference isn't really as staggering as everyone makes it out.....although the six pack rods are certainly heavier.
This has been argued back and forth in the ground. Here's how I like to put it. You'll never feel the difference in how the engine runs with six pack or stock rods. If you think the six pack rods hold a car back, you've never seen a box stock A12 car blowin the doors off the competition. Nuff said.
