For what your doing I'd go the 440 source stealth route. If you plan on increasing HP down the road I'd go with the Trick Flow 240's. I went 11.0s with a stock bottom end (Stock crank, rods and yes pistons (dumb, but I did it)) 67 motor and .533 hydraulic cam, older weiand single plane intake, 750 DP, 2" Hooker fender wells and 3250lb race weight.
