I don't really know what pistons i have , i've never had the heads off . I would guess there the stockers , everything else was . I need to get this big fella to 13.99 , so i can race bracket 4 . Lots of cars in bracket 4 , only about 7 or so in bracket 5 . I'd rather not get too deep into the motor at this time , better in the fall / winter.
