273 build ?????

I know nobody builds this motor but I am going to build mine.
Looking through the latest Summit catalouge they have lots of ford & chevy stuff but not much for mopar. I need to know where I can buy some 9.5:1 .030 over pistons for my 273. I think I have the rest of it sussed out but I would like eutectic pistons for this car. (cast would be fine too)
Any advice? DM
