'Match Race 1969' 440 'Cuda vs 440 'Six-Barrel' Road Runner

Seeing what I am seeing, Gears and weight the roadrunner was, (I did not know they was so light) and weight transfer I am going roadrunner on this one.
You all sold me, I know the first 60' will make or brake my opinion...
But way did Barracuda hold the fastest marketed car for Sox & Martin for 3 years ? Stock..
