Found this 383, worth it for my 65?

Thanks for those replies and steering me in the right direction. As for small block, what’s a good choice? 318/340/360 I see some people mention magnum? I would be wanting around 400-450 horse. I’ve built Chevy and ford engine, strokers and what not but never a Mopar engine. What best to look for and what should I stay away from?
