I didn't pick up the engine yet. But they told me that they are using the same ones as what was in but 60 over. I asked them to use a '68 4bbl piston if possible cause the pin height is lower. I'll measure them when I get it assembled next weekend.
A standard bore 72 and later 440 piston will give you a 1.93" compression height, same as 68 383 but it will be .070" over, I machined and built a lot of them and have another I'll be doing soon which will be for sale.
