I'd picked up a pile of engine parts this past summer, mostly from torn down B43G and P218G engines. Is there a 'table/list' of how to interpret the part numbers on the connecting rods as to what goes to what engine(s) and/or what size they are? Thanks, Bryan.

I don't have a table/list, but I can tell you that is the longer stroke rod, so could be used in B48G, P218G, or P220G. I don't think that number 170-4105 changes whether it is standard or undersize.

Thx 'charms' ... what tells you it's a longer stroke rod? Hoping to find a list/table of some sort so I don't have to ask all the time ... like to know how to interpret those numbers. Any idea on this one? Thx, Bryan.

The number 170-4105 is one of the numbers for the longer stroke rod. The 170-4444 rod is for the shorter stroke B43 engines.
Onanparts.com has good descriptions of what rods fit what, and which numbers replace older numbers. Note the part numbers are different from casting numbers.
