ok, so i know anything will work if you put enough money and effort into it, ha. but will it be more difficult than a same era engine swap? any extra parts i would need? thanks,

Not difficult. Use the '63 oil pan and oil pickup and complete engine mounts. If the '63 has an automatic transmission, you will need to use the 1/8" adaptor ring between the small '63 torque converter nose and the big '73 crankshaft counterbore. This can be had from Pat Blais, tflitepatty@verizon.net . Use the '63 carburetor so the throttle linkage will hook up.

I also have the adaptor rings for $20.00 each.
PM me if you need one.

The adaptor is a small, 2 inch ring, not a "plate".
