I have a 1965 273 short block in the garage with the domed 10:1 Commando style pistons that are 0.030" over. I haven't had it apart so don't know the history of the motor other than the man I got it from had it as a backup block for this custom race car.

My plans have changed and I don't need a 273 anymore so if you are interested in the used pistons, I could see about pulling the motor apart to see how the pistons look. I am not sure yet if I'm going to let the rods and crank go, but I definitely won't be using the pistons.
