My 273 Experiment

I don't know much about the 273 , so excuse if it's stupid , can you use pistons from another small block ? I like the idea of a 273 screamer , my mom had a 68 Dart convertible with the 273 4 bbl , I used to get her pissed off while driving cause when she would stomp on the gas and it smoked the tires , great little motor .
Go for the 273 , everyone has a 340 or 360
