If you "google" "409 chevy", or "409 chevy engine", lots of pages come up.

I went through a number of cars and engines many years ago. If you are just looking for the "look", avoid the High Performance engines. They were just too radical for today's gas, or normal street use. A set of headers, maybe some valve covers, and a mild cam with a single four, on a small port engine, will give you good reliable power, and look awesome!
