Trying to identify engine,help
 

Hello everyone, new member and i'm trying to identify what i believe to be a 454 truck engine but can't seem to make any sense out of the engine numbers which are T4478418.I've looked through a ton of engine codes for bb GM engine blocks and nothing is even close.Intake manifold # are 354483-1976,appreciate the help.

things to remember about casting numbers. There are no letters in the casting number so even though a number "1" may look like the letter "I" it is still a number "1". Same holds for the number "0" is not the letter "O". Also later blocks can have the size of the engine listed in liters at this location.
