Cobra Make, Engine: Unique Motorcars 289 USRRC, 1964 289 stroked to 331, toploader

Not Ranked

Well, according to John's numbers, 2.87" + 0.378" over the stock throw, the stroke is 3.248", which doesn't quite get to 327ci... but it is close! I figure you are backing the stroke out of the whole number displacements...
