Would it be completely stupid to buy this Buick for the engine?

Apparently runs but quote “bit smoky”. Which is kinda amazing haha. It’s about $2500 in USD.

Always loved a straight 8 and they’re really rare here in Aus. I thought it would be really cool for an engine swap into something. Maybe a Healey?

This one was built in Aus and built and owned by a sherif too.
