Homemade 340 ###

That’s it right there! And the block he used is also nearly as strong as an X block. It’s good to see this one go from what it was dismantled from to what it is now. It was a 1973 W300, Windsor plant engine that was used on a mine as a powder truck. And like he says, it saves the 340 for the restoration crowd.

There has never been a production block anywhere near as strong as an X block, let alone the R series blocks. Not even close.

Not even the T/A block was close to the X block. And I’ve seen a couple of the thick 360 blocks. Not one of them had pan rails any thicker than any other block.
