A small block would really be easier in the corners, and lighter in the front. Stroke it! I'm running a 340 stroked to a 416 (also 360's are easy to find (360 + 4.0 crank + 30 over bore = 408 cubes)). She'll run in the 11.teens all day (on pump gas!). With a four speed auto trans, and a lockup converter, that's still obtainable. You can cruse the high way easily too. I'm running a 8 3/4 rear end (never had a problem). I'm sure people out there have better suggestions for you, but keep your options open till you decide.
Good luck!
