what to do with my 273

I sorta wonder the same questions. Although I have a 340 on a stand, collecting parts waiting to be rebuilt, I've found an original date code correct 273 Commando, already rebuilt, for $1000 that would drop right into my car and make my car a numbers matching car! I'm not sure what I want to do now.....

How much horsepower can you expect to get from a 273?
