I'd rather have a 455 iron headed "street" build that idles well, and pulls hard to well past 5000rpms making nearly 90 MORE HP at the shift point. Not so mention torque production in the upper mid-range and top end is up nearly 60-100ft lbs at every point. The naysayers usually come back with "all I want is good low end torque" and not concerned with top end power. That's complete horsechit....IMHO. Why not make more power at every RPM with better idle quality and street manners? A 455 is also going to make more "low end" power than you can handle anyhow in just about any configuration. Things done to spread that power out and push some of it to higher RPM's only results in the vehicle being a LOT faster the day you decide to take it to the track and get some numbers on it.......FWIW......
