I am currently working on a '64 Ranchero which originally came equipped with a 170 cid 6cyl engine & Fordomatic trans. The engine was in trouble so I purchased a complete used engine which I believe to be a 200 cid. Correct me if I am wrong. Number on the block reads C6DE-6015-B. I had the Fordomatic 2-speed automatic trans completely rebuilt and want to use it behind the 200 which currently has a flywheel bolted to it since it was mated to a manual transmission. My question is after removing the flywheel can I simply transfer everything from the 170 to the 200 and bolt up the Fordomatic? By "everything" I guess that would mean just the plate that goes between the block and trans. Is there any reason to remove the pilot bushing in the 200? Thanks in advance for your input. The wife is really after me to get going on this or one day I will come home and "it will be gone".
