The 65 has the original 283 and was originally a 4speed but now is a
350 turbo(I'm in the process of converting it back to
an m20 muncie)
The 73 has #'s matching 350 4speed but
they are both put away for safekeeping and currently
runs a ZZ4 350 crate motor with an m20 muncie backing
it up. Location is Canada
