Mel, why would you want to? they take twice the babbitt and hammer out quicker because of that. There is plenty of light rods out there to replace those, unless you are after heavier weight for rotating mass?

Joe, when you say that they take more babbitt, I am assuming that the base ID diameter is larger?

Two types of heavy rods, C -type , pre-1915 have bore of 1 1/2" with 1/8" thick babbitt.

B-type, 1915-early 1920 heavy rods have same bore as the light rods (late 1920 and on), bore of those is 1 3/8" with 1/16" thick babbitt.

Well that explains something I have wondered about.
Back in the T era there were crankshafts made with 1-3/8” crank pins. The advertising implied that they could be used with T rods, and now I understand that this is true!!
Further I have one of these cranks!!
