Re: 1971 GTX SS/HA Anybody know this car
The NHRA file only shows a 71 Road Runner, no GTX listed.
But, for 1973, SS/HA=9.50 lb//hp
The Road Runner 440-6v/385hp meets this class with W/P=9.63
So that's my guess
The Hemi was always factored way above its 425hp rating (ROTFLMAO) so depending on factoring would likely be in the SS/EA=8.00 class.
Still lots of power in 1971 but everybody's cars were heavy except the Duster.
