I believe that would make it a 71 460, or possibly a 429 that someone put 460 heads on. Maybe someone else can confirm that or correct me if I am wrong. And Are you sure it is supposed to have a 289? 1970 would have been a 302, 1968 was the last year of the 289

That is probably a 1971 429 4V Thunderjet. If it has the factory flat top pistons that will be a high compression engine in excess of 10:1. With a stock cam you will definitely need to run 93 octane and be careful with the ignition timing to avoid pinging.
