'71 Duster 440 or 360? Pros and cons

BB advantages - you can say , I have a 440 Big Block, more torque
SB advantages - can go just as good or better, lighter, more room in the engine bay for better extractors etc
I have a 383 BB & wish it was a 340/360. Only good point as far as I'm concerned is the fact I can say "It's got a Big Block" - Big Deal!
