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

273 flat tops are 8.8 to CR. Best way to bump the CR up is either take a little off the heads (.020) amd run the .028 head gasket. Of course it would help to know the deck measurements. I had a stock 2bl 273 and all I did was change head gaskets and it made a world of differance, I could still run mid grade fuel.
