Guys running a 4.1" Crank. For those running a 4.1 crank where are you getting your custom pistons from and how much more did they cost? Also does the rod length stay at 6.125?

Like he said also they cost 100.00-250.00 more depending on how custom the piston is basically as in dome, dish or flat top as well.
It's an iron block, 4.03 bore. When i was first researching building a 418 I read a lot of people complainaing about piston skirt/ring wear with the longer stroke, is this because people were not buying the correct pistons or is this still an issue with the longer strokes?
