This is a chart for a SBC I-Con pistons and what you should be looking for in the box. 12-29-2012 11:44 AM

The people that have breakage problems with KB pistons are the people that don't read instructions or understand the design/construction of these pistons.

As mentioned, ring gap is a major consideration as is piston to wall clearance.

Stock and 4032 alloy cast hypereutectic, 11% silicon...........up to 450 HP
Aftermarket 2618 alloy forged, 2% silicon ........................up to 1200 HP

The choice is yours.

The feature I like on the I-Cons is the design of offset pins to limit cold piston slap.For the street,press fit pins are the way to go.
