Factory stroke is the same as the LS1/LS6 (they use the same crank). I have read that the 5.3 block can be bored out to the same size as the LS1, so you can make a 346 out of the stock stroke. Stroker cranks are available that will take it up to a 383, I think that is about the max for this block.

And yep, it's iron

Here ya go, stock bore x stroke

5.3 = 3.78" x 3.62"
