1971 Match Race ~ 'Duster 340' vs. 'Boss 351 Mustang'

O-M-R,

In 1972, in NHRA Pure Stock, both cars ran in B/Stock {10.00 to 10.99 Wt/Hp}

No Headers, as all 'factory' exhaust systems were required.

No Slicks, only D.O.T. treaded tires as wide as you could get, provided
that fit inside the rear well. L-60 series were popular.

And, the car had to be 'street-driven' to the Track.

Any gears allowed. But everything else, 'factory stock'.
