Well spotted JD, I did not even realise this, I just checked and yes they are a 360 piston. Thanks for picking that up, :thumbsup: I must have ordered the wrong ones years ago, or else Summit sent me the wrong ones. But I'm surprised that they are so well priced, as surely there wouldn't be many people boring out a 360 to +0.070 ? So I thought they would be more expensive due to limited demand.
Anyway that's a frustration as now I have to fork out another $450 for pistons and try to sell these but don't like my chances on many people wanting this large bore size. Anyone know what a stock 360 block can be comfortably bored to? I suppose it depends on the year and casting thickness.
