Match Race ~ 1970 'Duster 340' vs. 1969 Mustang 'Mach 1' 351W
Moper,
The 351W 'Mach 1' is carrying +272 lbs. more than the Duster 340.
Could be too much to overcome.
Also, the 'Mach 1' had a 57/43 {Front-to-Rear} Weight Distribution.
Even with the 'optional' F70 x 14" Tires, in Stock form, the Mach 1 would
have traction problems here.
