Sb/bb?

All right yall,
Here's my question, would you go SB or would ya go BB?
'70 Duster 340 originaly, now nothing but a rolling body. Originaly an auto. The car will be more of a street car. If I run a SB, I think I'm gonna lean toward a Comp Cams Thumpr series cam. :evil2: If BB, then it's open for discussion. I am far away from even getting a motor, but I would like to make up my mind so that way, when I jump on the front suspension, I know in what direction I am going to want to go. With a BB it needs to be more of a heavier duty front end, versus SB which doesn't way near as much, and doesn't have to be such heavy duty. Anyway, I will probably do a SB stroker, or a regular BB. Since the car doesn't weigh all that much at all, I want need massive amount of torque, versus my '72 Charger SE..... If I go SB, I may do a 360 block based stroker. I would rather go with a 340, but..... Trying to find one in good shape.... well... Yeah sure. 318 is nice, but that old quote "There's no replacement for displacement" comes into play. If I were building a strip only car, then BB would be no question. I like the idea of a BB Duster, but what would be more economical? The SB, or the BB? Anyway, I look forward to reading everyone's opinion on this matter. Also, as stated before, I plan on going to a tubular front end for more clearance, so headers and oil pan selection will be more of an endless matter, except for the BB.... Anyway, if there are any questions, please let me know.:rock:
