When Dom built my 4.6 with its original Pistons we talked about 4.0 Pistons, I'm sure he'll have some idea Ole.
10.5 comes to mind but I'm not really sure!

I reckon thats a good ball park figure but OLeVix you would have to check the actual motor in question for accuracy otherwise its not worth guesstimations
