my 72 BB challenger was 3850 with me in it! my 71 dart is 3450 with me in it(aluminum block)! take away the fact the block is prolly 100lbs lighter and the difference would be about 300lbs lighter! im guessing sb cars would follow suit! so ill say 300 range as already mentioned!

both of ya just go pull in junk yard scale at the same time and find out I guess!
