    LS1 crankshaft in an LS2/LS3 block?

    I know that 305 cranks shouldnt be used in a 350 because the 305 cranks are too light/lightly balanced for the 350@s heavier pistons, is this the same for the LS1 cranks for the LS2/3 blocks/pistons?

    You can use any of them, you just have to have them rebalanced for the pistons and rods if putting it in a different engine than what it came in.
