Now Taking Bets: '70 Hemi Road Runner vs. '72 Olds 442 W30

[Photon440]

Good point.

A true test should also include swapping drivers every other pass, or at least equal number of passes for each driver in each car.

That would only work if the driver wasn't partial to the make. An Olds fan isn't going to try too hard to get a Plymouth to win.
