The LM7 OEM reads a gap of 0.23-.044 mm. Mahle ( I have the 'Original Premium' Mahle rings) claims a .43 mm gap for a 96 mm bore. for "high performance street" Wiseco, who I'm using a reference claims .038 mm gap.
I am measuring .033 mm comfortably, .035 mm with what feels like excessive drag.
This is just a naturally aspirated street/highway pickup. I am comfortable with my measurements based of GM's documentation. Yet the aftermarket claims I'm just a hair too tight
