I think it really depends what you are looking for? A SB is lighter up in front, which in turn allows the car to handle much better on the track and street. A BB can give you gobs of torque and a sound like none other, but will not handle as well...Unless! you go with the aluminum lock and heads...then you the best of both worlds at the cost of both worlds

Ps.
Now there are always exceptions and there are some unreal motors out there that are SB's or smaller! For example: I own a 32' salt flat street rod that has a 144ci Dodge Turbo motor that make well over 700 hp at the wheel...ON GAS! I set three records this summer out on bonneville with average speeds of over 200mph!see it at RaceDeckracing.com I would love to build a Cobra for out there using this motor...I am confident I can get it over the 200 mark!
