There are several of us running 11's or better N/A. Notables Pat Gish 11.20's, Mike Harris 10.50's, me Frank Staton 11.90's last week first time at the track with my new setup in 90 + degree weather. There are several more. And running from stock short blocks to 400+ cubes. I don't care what bottom end you may have but if you don't have a good top end to support it, it does not matter. Having a good set of heads and properly spec'd cam makes all the difference in the world. Pat Gish runs a rebuilt stock short block with AI heads and cam and with lightening of the car but still able to be driven back and forth to the track and runs 11.20's N/A. Mike Harris at 10.50's is still streetible. I don't care what you put into the bottom end its what you do with the top end that's going to make your power.
