My Pete rebuild

I think Rawze reused his rods. I've never had a set of original assembled rods to use, they are not available new through Cummins, and buying RX's get you rebuilt rods that could have been manufactured over a 20+ year span.

The new block kit - the only way I could find to get a virgin block, comes with liners pre-installed, oil cooling nozzles & bolts, and dowels. The only advantage of buying a kit is that pistons would most likely all have the same date code and possibly vary a little less in weights. It would cost more because I would be buying new liners that I don't need.

And - I would still be faced with wide ranging rod weights.

Cummins is still producing new CM570's for export, but aside from snagging one of those on it's way out of the country, it's been pretty challenging to source all of the parts needed to make a brand new 14 year old model engine without going aftermarket.
