'65 Mustang Hi-po vs '65 Formula S
When I had my 1965 GT350 in California I knew in a drag race it would KILL my moms 1965 Barracuda Formula S. Both were 4 speeds. Both had 3.9x:1 posi type rear ends. Shelby had better tires and a better clutch. Shelby had more HP and Tq but was about 500 pounds heaver than the Barracuda.
But I also felt the way we had the Barracuda set up it would out corner the GT350. I drove both cars on Hy 1 from Monterey CA down thru Big Sir so I knew how they both took the corners.
My mom ordered the Barracuda with a trailer towing package. It had 5 leafs, 8 3/4 SureGrip with 3.91:1 gears. It had D78-14's on 4 corners. Small BP but 4 piston KH disc's up front.
We had a 1963 Airstream Bamby that was 13 foot long and the Barracuda pulled it just fine at 45 to 50 MPH if she avoided big hill starts, Clutch issues. I sold it back in 2015 for $18,000
