Hi folks! I'm new to the forum. I have a 1967 GS400 convt that is running a later 455 Stage 1 T/A engine. I just rebuilt the original 400 and plan to return my car to numbers matching soon. This would have left me with a spare 455 until I tripped across a nice 73 Apollo coupe with a 350. I am planning to drop the 455 into the Apollo; has anyone done this?? What problems should look for. gkelley
