Looking for a 1971 225 engine & trans

As far as column vs console shift, a 904 is a 904.
A trans that came from a column shift car can be used in a console shift and vise versa
And a slant 6 demon doesn't have the pedigree of let's say a hemi cuda or even that of an original 340 dart. If it has a /6 in it and it runs and drives well it isn't as important that it has the original one except for sentimental reason.
