Finally found all the #'s I think after a bit of scraping & a wire brush.
Engine Block casting # is 3835911
Block Date Casting Code - CON4 J263
Engine Serial # 0480771F54Z
Head Casting Code 370887 (Con 12) & (D213) are also stamped on the head.
Have a safe and happy 4th of July and many thanks for all your help
