273 3 speed column shift

I'm looking at buying a 66 barracuda that has a factory 3 speed manual on the column and 273 engine. Would like to swap a 360 into it and keep the 3 on the tree if possible. Is this possible? Also wondering how rare the 3 speed manual on the column is in the early cars, looking online they all seem to be 4 speeds when they got the V8.
