because mine has 15,000 miles on it and its not worth anything used.

i figure ill use it in a 364 build for my procharger to offset some cost for the additional conversion parts.

So you'd need to get the old LS1 crank re-balanced with the LS2 rods and pistons.

Is not the only issue the slightly heavier pistons? I thought the rods were the same?

Rods are probably the same, not sure....just included rods because you'd nomally take them with you when you got the rotating assembly balanced.

Essentially the same....probably have different balancing weights tho, due to different pistons used.
