5.3 piston ring help
I totally get opening the top ring up if the top ring has been moved up toward the crown. I just haven’t came across any eutectics that have the top ring moved up…not yet. The Mahle info you posted is stating that it’s current tech to open the second ring up larger than the top…but I’ve been doing that since I started cutting rings over 30 years ago.
I think I’ll call my machinist Monday and chat about this. He works for Gibbs as a consultant now. They spend over a million a year with JE. He will get me up to speed on this larger top gap.

Last time I built an engine using Mahle pistons and actually called them and the guy was basically on board with the current trend of larger 2nd gap than 1st also, was around 2015 or so. That was a NA only street built 383 (3.905" bore) that I wanted it to be sealed up tight for the guy. I set it up at 0.018" top and 0.022" 2nd.
