Block C3AE 6015 H seems to be a 390 service block, possibly for 390 PI engines.

They would all be car blocks as the FE wasn't in light trucks yet in '63. Not that car and light truck blocks differed much even at the end.
No cross bolts on the mains so no 427....
C2AE main cap = All flavors of FE mains, 2 bolt.
C1AE A rods are supposed to be the long rod as found in the 352/360.

I can't tell the difference in the images I can find and you never know if an internet image is really "right".
Depending on the piston, a long rod would work on top of the 390 stroke.
Can you measure the bore in any way?
What are the numbers on the heads and intake?
As OEM, a '63 390 might have been a 9.4 or 9.6 compression depending on 2V or 4V. Earlier and later engines got into the mid 10s.
