i'm curious as well. that's exactly what type of compression i'm looking for. you did't mention your heads and what's the combustion chamber volume. by me living in detroit, mi, i'm just 15 minutes away from diamond pistons and i think i'm going with them. i'm using trick flow a heads and they have the ability to custom make pistons that will totally fill the chambers. between $900-$1,000 a set though for the lightweight pistons.

Diamond can make what you need, after I showed them how. If your heads work very good at all though, I would use a 118 motor octane with iron heads if your very close to 15 or more to 1.
