No one seems to know?

that includes running a 7.25 on a 360 Bcuda. I am not a 'want to be drag racer' but have done the occasional burnout etc. I asked the weight difference since the 8.75 are so pricey but finding a narrow 8.25 is probably not easy either. Someone mentioned 60-70 lbs difference, but that may have been between the 7.25 and 8.75-not sure, and it appears that no one has really weighed them. I tried to find the specs but could not. George
