I think a lot has to do with what you're using the car for. I have a 470"BB in a 69 B'cuda with a 4spd. Aluminum heads,intake waterpump, radiator,etc really help keep weight off the front. I did the disc brake conversion with big bolt wheels. Added frame connectors and front/rear sway bars from Hellwig. So it drives great....goes around corners OK and oh yeah, it does this really good Big block torque in a little package can be a lot of fun!
