Saved from a garden being removed

Got this bad boy from a house that was having the whole garden removed. I think it's a Trichocereus Pasacana. I have to figure out exactly where to put him too. And enlist a friend to help, It's about 3 feet tall and pretty heavy! Also the spines are about 10-12cm so I can't really chuck it around on my own. I had to prop it up becuse it doesn't really fit in a pot due to the way it curves quite a bit at the bottom of the column where the roots are.

You could be right, the long spines it's developing do make it look like Echinopsis atacamensis which is a sysnonym for pasacana..

Whatever it is, it surely is a nice find. The plant looks healthy with a nice green colour, and those spines... brutal!

Yeah, i was super happy to find it. I walked out the back of the house down to the end of the garden and behind two huge, sprawling euphorbias this little guy was just doing his own thing. He jumped out from the rest of the garden as a "must have" to me.

My friend, who was with me at the time, also got a 5-6 foot column of Pachycereus marginatus which looks pretty cool too.
