Knowing that the 935's of the 70's were capable of reaching speeds close to 230 mph with an almost identical body as that of Blackbird I have no doubt that areo will not be a major factor in this piticular race. These are two of the same breed and the differences in areo is dimunitive at best. Its not like we are compairing a 68 Roadrunner with a Lambo. I think Bello will have his hands full with a well sorted and dialed in Blackbird.
