Hello. I am considering buying an original 1966 Fairlane GT that has a 390 engine in it. I was wondering whether or not the '66 390 engine is a desirable engine or not and was also wondering what kind of parts I would need to build a 550hp monster engine. I would like for the engine to be streetable and be able to run along with the top-loader 4-speed that is in the car. Thanks.
