'71 Duster 440 or 360? Pros and cons

There's no replacement for....well,how many times have you heard that before.If it were me,I'd do it.The 440 is going to be so much more fun on the highway and driving around town.I love that big block torque when you're cruising down the highway and you "test out" the passing gear.The biggest concern is the clearance issues on oil pan,exhaust,etc..I have a 71 Demon that I'm going to pro street,back half,4 link,blah,blah,blah.I plan on putting a stroker B motor in it though.Look at it this way,if you don't like the 440 then you can always put the 360 back in it.At least try it out.
