Big smallblock power..Turbo?

Turbo and a 5 speed sounds like fun to me.
I get on turboforums quite a bit and can tell you that there is a lot of good running smallblocks cars and trucks on there.
My personal reason for going turbo on my duster was seeing all the power and streetablility of turbocharging. I have a custom turbo grind in my 440 that idles like stock and will be running a 3.55 gearset with an overdrive A518 in it. I am going to EFI next for total streetablility. There is a guy with a purple challenger with 500ci big block turbo that was cranking out 800+ wheel horsepower and was getting 18 mpg on the highway with efi and a 5 speed.
