Searched the online series 5 wsm for specs on the 1725 crank journal dimensions. Seems not to be included.
are they the same as for the 1594 crank?

BD,
No, they are different dimensions.
For perspective, the 1725 mains split the difference between small and large journal SBC cranks. The crank pins are larger than even a large journal SBC crank pin.
Hope this helps,

Ok, thanks. That is what I need. Trying to keep the crank standard as my shop can't grind cranks.
Lucky to have a machine shop here. All the old guys have retired or dead.

Before anybody grinds their crank - or installs new bearings - I strongly suggest you MEASURE YOUR NEW BEARINGS. I've found serious discrepancies between what's on the box, and what the ACTUAL dimensions of the bearing shells are, particularly with newly manufactured shells. When I built my engine, I installed the bearing shells, then measured them with a dial bore indicator, marked all the shells as to position, then cut the crank to match each of the shell pairs (less .001" clearance for oil). If you cut it to a 'standard' size you may find that you've cut too much... and that's a bad thing.
