/6 Build Question?

I have a couple of /6 cars and I have been thinking about the engines in them.

Isn't about one HP per CID a good rule on those while still maintaining good drivability?

I ask this because I remember Hot Rod's build up of a /6 Duster a few years ago. It seems they stripped it and got it to run 13.90's.

What are you guys running in the quarter with /6 cars? MPG?

Most I see run in the 14's, but I'm just curious as to what you have achieved.

Thanks, ROB
