Hi Jerry, No responses yet. I think that the engine is a 426 or a bored out 413, but I am not going to remove a head to find out. I was hoping that the piston # might tell me.

The number that is visible is "E8310" followed by a symbol that looks like the lower half of a small case letter u. The letter "A" is beneath the number. Could they be aluminum? The block casting # is 1852029 and has been rebuilt.
