Personally I would choose a turbo over a blower. My v6 turbo in my regal makes upward of 400hp and over 450ft/lbs of torque at 25psi of boost. And alcohol injection allows me to do all this on pump gas. I won't promise that on a 235 or 261, but it will be easier for you to make more usable HP and torque for the street with a turbo. You compare the supercharged torque ratings of a 231 v6 to a grand national engine and the turbo engine makes over 100ft/lbs of torque than the supercharged version. Just some food for thought.
