Group,I have a set of +.030" forged pistons and I am about to have the barrells bored to suit.In the Corvair shop manual the piston to bore clearances are given as: Top land .022" to .031"and the skirt: .0011" to .0017".I'm sure I recall reading somewhere that forged pistons require greater clearances but I can't find where I read it.Could someone who has rebuilt their own Corvair using forged pistons (or anyone who has the knowledge) please clue me up on this.Many thanks,Rod WoollerChidlowAustraliaHot chart ringtones and polyphonics.

Hi Rod I have built several V8 Ford and Chevy engines with forged pistons. Because the aluminum is denser than cast pistons they expand more when heated. the piston manufacturer should supply the clearance information. All of the forged pistons I have installed called for .005" skirt clearance. You can actually hear them rattleing in the engine when they are cold which I personally dont like but they quiet down when they are hot from being loaded. Hope this is of some help.
