Attention Engine builders. Piston skirt clearance?
Posted: July 2nd, 2015, 7:45 am
I know forged pistons are louder on start up than cast or Hypers but I am wondering what the preferred clearance is for good street performance? They are 4032 forged pistons for a 4.0 rod and 4.2 crankshaft and metric moly ring package. Whats the magic number?
