Some of the big guys sell a "copy" built by any number of "bulk builders" but my guys havent had them for a few years. They ran out of new blocks(presumably) because they started using and building remans for the last couple of years. They came with oversize pistons, not sure about crank or heads but saw a few 4.030 or 4.040 ones. Like I mentioned, a used factory short block with no issues, then aforementioned parts will make an easy 400HP.
