What do I need to change to a 454 in a 76 blazer currently with a 350 4 brl this truck has an 86 motor in it right now so I have the one piece rear main seal and probably a flyweel to match that motor it was in it when I bought the truck it also already has an electric fuel pump mounted on the frame I would like to change this to a 454 should I look for a newer 454 or an older one and change flywheel back.
