Not Ranked

By the way........this is based on the 289 going 7000 rpm in hi gear.........

8.2x15 tire is 29.6" dia. (www.rogerkrausracing.com/oldtire)
29.6" x 3.14 = 7.74'/rev
7000rpm / 3.09 rear gearing = 2265 revs/min
2265 / 60 sec = 37.75 rev/sec
37.75 r/sec x 7.74' = 292.18 '/sec

292.18 '/sec x 0.6818 = 199.2 mph
